From: Giridhar Malavali <gmalavali@xxxxxxxxxxx>
commit ffc81fc07efc94a04695a8c1d458a06aecaf9f30 upstream.
This patch sets remote_port_devloss value to 0. This indicates to FC-NVMe
transport that driver is unloading and transport should not retry.
Fixes: e476fe8af5ff ("scsi: qla2xxx: Fix unload when NVMe devices are configured")
