[PATCH 5.19 0620/1157] scsi: qla2xxx: edif: Fix no login after app start

[Greg Kroah-Hartman]

From: Quinn Tran <qutran@xxxxxxxxxxx>

[ Upstream commit 24c796098f5395477f7f7ebf8e24f3f08a139f71 ]

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.
