signal: zap_pid_ns_processes: s/SEND_SIG_NOINFO/SEND_SIG_FORCED/
Change zap_pid_ns_processes() to use SEND_SIG_FORCED, it looks more clear compared to SEND_SIG_NOINFO which relies on from_ancestor_ns logic send_signal(). It is also more efficient if we need to kill a lot of tasks because it doesn't alloc sigqueue. While at it, add the __fatal_signal_pending(task) check as a minor optimization.
