[PATCH] Remove always false check in mm/slab.c

  CC      mm/slab.o
mm/slab.c: In function `kmem_cache_create':
mm/slab.c:1129: warning: comparison of unsigned expression < 0 is always false

This comes from the fact that 'align' is size_t and so unsigned. Just to be
sure, I did
	$ grep __kernel_size_t include/*/posix_types.h
and yes, every arch defines that to be unsigned.
