Subject: [PATCH AUTOSEL 4.19 16/34] scsi: qla2xxx: Don't call qlt_async_event twice

From: Roman Bolshakov <r.bolshakov@...ro.com>

[ Upstream commit 2c2f4bed9b6299e6430a65a29b5d27b8763fdf25 ]

MBA_PORT_UPDATE generates duplicate log lines in target mode because
qlt_async_event is called twice. Drop the calls within the case as the
function will be called right after the switch statement.
