[PATCH v3] lpfc: Tie in to new dev_loss_tmo interface in nvme transport

[James Smart]

This patch calls the new nvme transport routine for dev_loss_tmo
whenever the SCSI fc transport calls the lldd to make a dynamic
change to a remote ports dev_loss_tmo.

Signed-off-by: James Smart <james.smart@broadcom.com>

---
This lpfc patch, as dependent upon the new nvme transport
nvme_fc_set_remoteport_devloss() call, should enter via nvme-4.15

v2/v3:
  Ensure nvme_fc is enabled for compilation
