Subject: [PATCH 5.15 424/779] scsi: qla2xxx: edif: Fix no logout on delete for N2N

From: Quinn Tran <qutran@...vell.com>

[ Upstream commit ec538eb838f334453b10e7e9b260f0c358018a37 ]

The driver failed to send implicit logout on session delete. For edif, this
failed to flush any lingering SA index in FW.

Set a flag to turn on implicit logout early in the session recovery to make
sure the logout will go out in case of error.
