Subject: qla2xxx: synchronize rport dev_loss_tmo setting
Patch-mainline: submitted - 2021-07-02 - https://patchwork.kernel.org/project/linux-scsi/patch/20210702092052.93202-1-dwagner@suse.de/
References: bsc#1182470 bsc#1185486
Currently, the dev_loss_tmo setting is only ever used for SCSI
devices. This patch reshuffles initialisation such that the SCSI
remote ports are registered before the NVMe ones, allowing the
dev_loss_tmo setting to be synchronized between SCSI and NVMe.

[lkp: Do not depend on nvme_fc_set_remoteport_devloss() for !NVME_FC]
