Paul E. McKenney cdacbe1f91 rcu: Add fastpath bypassing funnel locking 
In the common case, there will be only one expedited grace period in
the system at a given time, in which case it is not helpful to use
funnel locking.  This commit therefore adds a fastpath that bypasses
funnel locking when the root ->exp_funnel_mutex is not held.
