OK, so I definitely confirmed: if your patch does anything, it
introduces a new deadlock possibility. Just trigger a Wifi timeout or
reset from within remove(), and you'll see the work event get stuck in
pci_reset_function(), while remove() gets stuck at cancel_work_sync().

I also confirmed that my patch resolves this problem.

I'll send the revert + my patch now.
