[PATCH v3 05/13] mm/slab: Simplify create_kmalloc_cache() args and make it static

[Catalin Marinas]

create_kmalloc_cache() is now only called from new_kmalloc_cache() in
the same file, so make it static. In addition, the useroffset argument
is always 0 while usersize is the same as size. Remove them.
