Fix signal unblock leak in failover.

When failover event occurs, register_node_operation_request() gets
called to en-queue failover/failback requests. If the request queue is
full, this function returns false with unlocking semaphore. But it
forgot to unblock signal mask. This leads to block all signals
including SITERM, which makes pgpool fail to shutdown.
