Well, only if the LLD previously did a remove of the device, which I
don't think it will have done.

I'd really like to see all fibre events (like loop up/down, device
add/remove) handled inside the FC transport class.  From there, it
probably still make sense to use hotplug as the mechanism for importing
user policy.
