iwlwifi: mvm: add inactive state to ebs status
Currently EBS status in scan complete notifications is set to
success if EBS wasn't activated. FW will add a special return
value for cases when EBS wasn't activated and we add a print
of this status.
This change is needed for debug only, no behavior changes.
