mm/slab: move kfree() from slab_common.c to slub.c
This should result in better code. Currently kfree() makes a function
call between compilation units to __kmem_cache_free() which does its own
virt_to_slab(), throwing away the struct slab pointer we already had in
kfree(). Now it can be reused. Additionally kfree() can now inline the
whole SLUB freeing fastpath.
Also move over free_large_kmalloc() as the only callsites are now in
slub.c, and make it static.
