rcu: rcu_sched_grace_period(): kill the bogus flush_signals()

As a kernel thread, rcu_sched_grace_period() runs with all signals ignored.
It can never receive a signal even if it sleeps in TASK_INTERRUPTIBLE, it
needs the explicit allow_signal() to be visible for signals.

[ Impact: reduce kernel size, remove dead code ]
