scsi: qla2xxx: edif: Send LOGO for unexpected IKE message
[ Upstream commit 2b659ed67a12f39f56d8dcad9b5d5a74d67c01b3 ]
If the session is down and the local port continues to receive AUTH ELS
messages, the driver needs to send back LOGO so that the remote device
knows to tear down its session. Terminate and clean up the AUTH ELS
exchange followed by a passthrough LOGO.
