Subject: [PATCH 07/16] mm: memcg: move memcg_kmem_bypass() to memcontrol.h

To make the memcg_kmem_bypass() function available outside of
the memcontrol.c, let's move it to memcontrol.h. The function
is small and nicely fits into static inline sort of functions.

It will be used from the slab code.
