Paul E. McKenney be975448a4 srcu: Document __srcu_read_{,un}lock_fast() implicit RCU readers ...

This commit documents the implicit RCU readers that are implied by the
this_cpu_inc() and atomic_long_inc() operations in __srcu_read_lock_fast()
and __srcu_read_unlock_fast().  While in the area, fix the documentation
of the memory pairing of atomic_long_inc() in __srcu_read_lock_fast().
