5.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Himanshu Madhani <hmadh...@marvell.com>
commit ec322937a7f152d68755dc8316523bf6f831b48f upstream.
This patch fixes LUN discovery when loop ID is not yet assigned by the
firmware during driver load/sg_reset operations. Driver will now search for
new loop id before retrying login.
Fixes: 48acad099074 ("scsi: qla2xxx: Fix N2N link re-connect")
