scsi: qla2xxx: Use complete switch scan for RSCN events
This patch removes unnecessary code to handle RSCN, instead performs full scan everytime driver receives RSCN Fixes: d4f7a16aeca6f ("scsi: qla2xxx: Remove ASYNC GIDPN switch command") Cc: stable@vger.kernel.org #4.19 Signed-off-by: Quinn Tran <qtran@marvell.com> Signed-off-by: Himanshu Madhani <hmadhani@marvell.com> Signed-off-by: Martin K.
