[PATCH 1/3] srcu: Remove superfluous ssp initialization on deferred work queue

[Frederic Weisbecker]

When an ssp has already started a grace period and queued an early work
to flush after SRCU workqueues are created, we expect the ssp to be
properly initialized already. So we can skip this step at this stage.
