scsi: qla2xxx: edif: Fix no login after app start

Browse Source 
The scenario is this: User loaded driver but has not started authentication
app. All sessions to secure device will exhaust all login attempts, fail,
and in stay in deleted state. Then some time later the app is started. The
driver will replenish the login retry count, trigger delete to prepare for
secure login. After deletion, relogin is triggered.

For the session that is already deleted, the delete trigger is a no-op. If
none of the sessions trigger a relogin, no progress is made.

Add a relogin trigger.
