rcu: Further cleanups of use of lastcomp
Now that a copy of the rsp->completed flag is available in all
rcu_node structures, make full use of it. It is still
legitimate to access rsp->completed while holding the root
rcu_node structure's lock, however.
Also, tighten up force_quiescent_state()'s checks for end of
current grace period.
