signals: do_signal_stop(): use signal_group_exit()
do_signal_stop() needs signal_group_exit() but checks sig->group_exit_task.
This (optimization) is correct, SIGNAL_STOP_DEQUEUED and SIGNAL_GROUP_EXIT
are mutually exclusive, but looks confusing. Use signal_group_exit(), this
is not fastpath, the code clarity is more important.
