scsi: qla2xxx: Synchronize rport dev_loss_tmo setting

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.
