srcu: Create an srcu_expedite_current() function
This commit creates an srcu_expedite_current() function that expedites
the current (and possibly the next) SRCU grace period for the specified
srcu_struct structure. This functionality will be inherited by RCU
Tasks Trace courtesy of its mapping to SRCU fast.
If the current SRCU grace period is already waiting, that wait will
complete before the expediting takes effect. If there is no SRCU grace
period in flight, this function might well create one.
