rcu: Adjust force_quiescent_state() locking, step 1
This causes rnp->lock to be held on entry to
force_quiescent_state()'s switch statement. This is a first
step towards prohibiting starting grace periods while
force_quiescent_state() is executing, which will reduce the
number and complexity of races that force_quiescent_state() is
involved in.
