rcu: Remove expedited grace-period fast-path forward-progress helper

Browse source 
Now that the expedited grace-period fast path can only happen during
the pre-scheduler portion of early boot, this fast path can no longer
block run-time RCU Trace grace periods.  This commit therefore removes
the conditional cond_resched() invocation.
