ionic: fire watchdog again after fw_down

Browse source 
In some cases of fw_down it was called because there was a
fw_generation change, and the firmware is already back up.
In order to keep the down time to a minimum, don't wait for
the next watchdog polling cycle, fire another watchdog off
as soon as we can - an out-of-cycle check won't hurt, and
may well speed up the recovery.
