slab.h: remove duplicate kmalloc declaration and fix kernel-doc warnings

Browse Source 
Fix kernel-doc warning for duplicate definition of 'kmalloc':

  Documentation/DocBook/kernel-api.xml:9483: element refentry: validity error : ID API-kmalloc already defined
  <refentry id="API-kmalloc">

Also combine the kernel-doc info from the 2 kmalloc definitions into one
block and remove the "see kcalloc" comment since kmalloc now contains the
@flags info.

/**
* kmalloc - allocate memory
* @size: how many bytes of memory are required.
* @flags: the type of memory to allocate (see kcalloc).
* @flags: the type of memory to allocate.
*
* kmalloc is the normal method of allocating memory
* for objects smaller than page size in the kernel.
*
* The @flags argument may be one of:
*
* %GFP_USER - Allocate memory on behalf of user. May sleep.
*
* %GFP_KERNEL - Allocate normal kernel ram. May sleep.
*
* %GFP_ATOMIC - Allocation will not sleep. May use emergency pools.
* For example, use this inside interrupt handlers.
*
* %GFP_HIGHUSER - Allocate pages from high memory.
*
* %GFP_NOIO - Do not do any I/O at all while trying to get memory.
*
* %GFP_NOFS - Do not make any fs calls while trying to get memory.
*
* %GFP_NOWAIT - Allocation will not sleep.
*
* %GFP_THISNODE - Allocate node-local memory only.
*
* %GFP_DMA - Allocation suitable for DMA.
* Should only be used for kmalloc() caches. Otherwise, use a
* slab created with SLAB_DMA.
*
* Also it is possible to set different flags by OR'ing
* in one or more of the following additional @flags:
*
* %__GFP_COLD - Request cache-cold pages instead of
* trying to return cache-warm pages.
*
* %__GFP_HIGH - This allocation has high priority and may use emergency pools.
*
* %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
* (think twice before using).
*
* %__GFP_NORETRY - If memory is not immediately available,
* then give up at once.
*
* %__GFP_NOWARN - If allocation fails, don't issue any warnings.
*
* %__GFP_REPEAT - If allocation fails initially, try once more before failing.
*
* There are other flags available as well, but these are not intended
* for general use, and so are not documented here. For a full list of
* potential flags, always refer to linux/gfp.h.
