Remove the function _rtw_zvmalloc from os_dep/osdep_service.c, as this
function is now unused and is just an inline wrapper around vmalloc
which zeroes out the memory. All previous callers have been converted to
use vzalloc. Also remove the declaration from include/osdep_service.h.
It is considered generally bad practice to declare functions as inline in
the majority of cases, as not only can this qualifier be ignored by the
compiler but the compiler generally makes good decisions about inlining
anyway.

Convert all rtw_zvmalloc calls within the driver to use the existing
kernel vzalloc function, which has the same semantics. Also rewrite the
two places where it is mentioned in comments to say vzalloc, and remove
the redundant cast to struct adapter * in ./os_dep/usb_intf.c as vzalloc
returns void *.
The reason for the conversion is that rtw_zvmalloc is just a
preprocessor definition for _rtw_zvmalloc which itself is just an inline
wrapper around vmalloc which then zeroes the memory out. As vzalloc does
the same thing via usage of __GFP_ZERO, this code is redundant and can
subsequently be removed.

Remove the function _rtw_vmalloc from os_dep/osdep_service.c, converting
its only user (also in os_dep/osdep_service.c) to use plain vmalloc.
This function is just an inline wrapper around vmalloc which returns a u8
pointer, which isn't needed. Also remove the declaration from
include/osdep_service.h.

Convert the only call to rtw_vmalloc in os_dep/ioctl_linux.c to the
kernel's existing vmalloc function, as rtw_malloc is just a preprocessor
definition for _rtw_vmalloc. The _rtw_vmalloc function is defined inline
and returns a u8, wrapping standard vmalloc. This behaviour is not necessary.

Remove empty function rtl8188eu_free_xmit_priv from hal/rtl8188eu_xmit.c
and its declaration from include/rtl8188e_xmit.h, as well as the one
place where it is stored in the free_xmit_priv function pointer of the
HalFunc struct inside padapter. This is safe, as the wrapper function
checks for NULL before calling this function via the function pointer.

Remove _dbg_dump_tx_info from hal/rtl8188e_xmit.c as it is just a
dumping function that contains a lot of unclear DBG_88E calls, and has
no other external effect, other than calling a function that ultimately
determines whether or not to dump/trigger the DBG_88E calls. Also remove
its declaration and single call site.

Fix buf allocation size (it needs to be 2 bytes larger). Found when
__alloc_size() annotations were added to kmalloc() interfaces.

Remove all the code related to the management of the NAT25_LOOKUP
method in nat25_db_handle(). The only function that used that method was
the now deleted nat25_handle_frame(). Remove the NAT25_LOOKUP entry from
the NAT25_METHOD enum because it is not anymore used everywhere else in
the code of the driver.
Remove the 'sender' pointer to integer. Remove
__nat25_db_network_lookup_and_replace(). Following the deletion of the
code related to the NAT25_LOOKUP method, they are no more needed.

Commit 0a0a66c984 ("clk: staging: Specify IOMEM dependency for Xilinx
Clocking Wizard driver") introduces a dependency on the non-existing config
IOMEM, which basically makes it impossible to include this driver into any
build. Fortunately, ./scripts/checkkconfigsymbols.py warns:
IOMEM
Referencing files: drivers/staging/clocking-wizard/Kconfig
The config for IOMEM support is called HAS_IOMEM. Correct this reference to
the intended config.
