[RFC,31/32] mm/slub: Simplify struct slab slabs field definition

Commit Message

Before commit b47291ef02b0 ("mm, slub: change percpu partial accounting from
objects to pages") we had to fit two integer fields into a native word size, so
we used short int on 32-bit and int on 64-bit via #ifdef. After that commit
there is only one integer field, so we can simply define it as int everywhere.
