tty: fix leakage of -ERESTARTSYS to userland
Spotted by Satoru Takeuchi.
kill_pgrp(task_pgrp(current)) sends the signal to the current's thread
group, but can choose any sub-thread as a target for signal_wake_up().
This means that job_control() and tty_check_change() may return
-ERESTARTSYS without signal_pending().
