[PATCH 5.15 750/917] scsi: qla2xxx: edif: Fix app start fail

[Greg Kroah-Hartman]

From: Quinn Tran <qutran@xxxxxxxxxxx>

[ Upstream commit 8e6d5df3cb32dddf558a52414d29febecb660396 ]

On app start, all sessions need to be reset to see if secure connection can
be made. Fix the broken check which prevents that process.
