ionic: catch transition back to RUNNING with fw_generation 0
In some graceful updates that get initially triggered by the
RESET event, especially with older firmware, the fw_generation
bits don't change but the fw_status is seen to go to 0 then back
to 1. However, the driver didn't perform the restart, remained
waiting for fw_generation to change, and got left in limbo.
This is because the clearing of idev->fw_status_ready to 0
didn't happen correctly as it was buried in the transition
trigger: since the transition down was triggered not here
but in the RESET event handler, the clear to 0 didn't happen,
so the transition back to 1 wasn't detected.
Fix this particular case by bringing the setting of
idev->fw_status_ready back out to where it was before.
