52b0c4709d staging: exfat: remove fs_func struct. 
Remove 'fs_func struct' and change indirect calls to direct calls.

The following issues are described in exfat's TODO.
> Create helper function for exfat_set_entry_time () and
> exfat_set_entry_type () because it's sort of ugly to be calling the same functionn directly and other code calling through  the fs_func struc ponters ...

The fs_func struct was used for switching the helper functions of fat16/fat32/exfat.
Now, it has lost the role of switching, just making the code less readable.

1af73a25e6 staging: exfat: fix multiple definition error of `rename_file' 
`rename_file' was exported but not properly namespaced causing a
multiple definition error because `rename_file' is already defined in
fs/hostfs/hostfs_user.c:

ld: drivers/staging/exfat/exfat_core.o: in function `rename_file':
drivers/staging/exfat/exfat_core.c:2327: multiple definition of
`rename_file'; fs/hostfs/hostfs_user.o:fs/hostfs/hostfs_user.c:350:
first defined here
make: *** [Makefile:1077: vmlinux] Error 1

This error can be reproduced on ARCH=um by selecting:

CONFIG_EXFAT_FS=y
CONFIG_HOSTFS=y

Add a namespace prefix exfat_* to fix this error.

74179976b0 drivers/staging/exfat: Replace more binary semaphores with mutexes 
At a slight footprint cost (24 vs 32 bytes), mutexes are more optimal
than semaphores; it's also a nicer interface for mutual exclusion,
which is why they are encouraged over binary semaphores, when possible.
There is also lockdep support.

For both f_sem and b_sem, their semantics imply traditional lock
ownership; that is, the lock owner is the same for both lock/unlock
operations and not under irq contexts (ie for trylock/unlock scenarios).
Therefore it is safe to convert.
