mm/slab: Move kvfree_rcu() into SLAB

Move kvfree_rcu() functionality to the slab_common.c file.

The reason of being kvfree_rcu() functionality as part of SLAB is
that, there is a clear trend and need of closer integration. One
of the recent example is creating a barrier function for SLAB caches.

Another reason is to prevent of having several implementations of
RCU machinery for reclaiming objects after a GP. As future steps,
it can be more integrated(easier) with SLAB internals.
