Subject: [PATCH 5.15 680/779] scsi: qla2xxx: Fix losing FCP-2 targets during port perturbation tests

From: Arun Easi <aeasi@...vell.com>

commit 58d1c124cd79ea686b512043c5bd515590b2ed95 upstream.

When a mix of FCP-2 (tape) and non-FCP-2 targets are present, FCP-2 target
state was incorrectly transitioned when both of the targets were gone. Fix
this by ignoring state transition for FCP-2 targets.
