IB/hfi1: Correct error calldown locking

The resource specific wait locking missed correcting the lock
for the notify_error_qp() calldown.

The code is fixed to correctly use the iowait lock field to protect
the head that is protected by that lock.

Fixes: Commit 4e045572e2c2 ("IB/hfi1: Add unique txwait_lock for txreq events")
