rcu: Remove CPU-hotplug failsafe from force-quiescent-state code path
Now that quiescent states for newly offlined CPUs are reported either when that CPU goes offline or at the end of grace-period initialization, the CPU-hotplug failsafe in the force-quiescent-state code path is no longer needed. This commit therefore removes this failsafe. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
