signal: skip blocked signals in dequeue_synchronous_signal()
dequeue_synchronous_signal() checks whether an unblocked
synchronous signal is pending, but its queue scan can select a
different blocked entry with a positive si_code. This can deliver
a signal while it is still blocked.
Check the blocked mask for each queued entry. Forced faults
are unblocked when necessary by force_sig_info_to_task(), and the
existing pending bookkeeping is unchanged.
