Subject: scsi: qla2xxx: Fix erroneous link down

From: Quinn Tran <qutran@xxxxxxxxxxx>

commit 3fbc74feb642deb688cc97f76d40b7287ddd4cb1 upstream.

If after an adapter reset the appearance of link is not recovered, the
devices are not rediscovered.  This is result of a race condition between
adapter reset (abort_isp) and the topology scan.  During adapter reset, the
ABORT_ISP_ACTIVE flag is set.  Topology scan usually occurred after adapter
reset.  In this case, the topology scan came earlier than usual where it
ran into problem due to ABORT_ISP_ACTIVE flag was still set.

kernel: qla2xxx [0000:13:00.0]-1005:1: Cmd 0x6a aborted with timeout since ISP Abort is pending
kernel: qla2xxx [0000:13:00.0]-28a0:1: MBX_GET_PORT_NAME failed, No FL Port.
kernel: qla2xxx [0000:13:00.0]-286b:1: qla2x00_configure_loop: exiting normally. local port wwpn 51402ec0123d9a80 id 012300)
kernel: qla2xxx [0000:13:00.0]-8017:1: ADAPTER RESET SUCCEEDED nexus=1:0:15.

Allow adapter reset to complete before any scan can start.
