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

[PATCH] 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

please disregard. A v2 that ensures CONFIG_NVME_FC is enabled is on its way
