I'd assumed that events wouldn't come in until ->scan_start was called.
I see lpfc doesn't have one; is it possible to restructure it to have one?
(In any case, good job tracking this down; it was really annoying me.)
Possibly we should be less forgiving, and require drivers to have a
scan_start, otherwise they can't avoid this race.
