io-wq: ensure we exit if thread group is exiting

Dave reports that a coredumping workload gets stuck in 5.15-rc2, and
identified the culprit in the Fixes line below. The problem is that
relying solely on fatal_signal_pending() to gate whether to exit or not
fails miserably if a process gets eg SIGILL sent. Don't exclusively
rely on fatal signals, also check if the thread group is exiting.
