io-wq: exclusively gate signal based exit on get_signal() return
io-wq threads block all signals, except SIGKILL and SIGSTOP. We should not
need any extra checking of signal_pending or fatal_signal_pending, rely
exclusively on whether or not get_signal() tells us to exit.
The original debugging of this issue led to the false positive that we
were exiting on non-fatal signals, but that is not the case. The issue
was around races with nr_workers accounting.
Fixes: 87c169665578 ("io-wq: ensure we exit if thread group is exiting")
Fixes: 15e20db2e0ce ("io-wq: only exit on fatal signals")
