From: Hannes Reinecke <hare@suse.de>

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]
Reported-by: kernel test robot <lkp@intel.com>
---

This patch got some more testing by one of our partners. So far, no
regression identified.

changes v2:
 - fixed build failure for !NVME_FC reported by lkp
