slab, rcu: move TINY_RCU variant of kvfree_rcu() to SLAB
Following the move of TREE_RCU implementation, let's move also the
TINY_RCU one for consistency and subsequent refactoring.
For simplicity, remove the separate inline __kvfree_call_rcu() as
TINY_RCU is not meant for high-performance hardware anyway.
Declare kvfree_call_rcu() in rcupdate.h to avoid header dependency
issues.
Also move the kvfree_rcu_barrier() declaration to slab.h
