mm/slab: simplify create_kmalloc_cache() args and make it static
In the slab variant of kmem_cache_init(), call new_kmalloc_cache() instead
of initialising the kmalloc_caches array directly. With this,
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.
