[PATCH 2/3] mm, slub: unify access to s->cpu_slab by replacing raw_cpu_ptr() with this_cpu_ptr()

[Wei Yang <richard.weiyang@xxxxxxxxx>]

In current code, we use two forms to access s->cpu_slab

  * raw_cpu_ptr()
  * this_cpu_ptr()

This patch unify the access by replacing raw_cpu_ptr() with
this_cpu_ptr().
