Subject: scsi: lpfc: Fix propagation of devloss_tmo setting to nvme transport
Patch-mainline: v5.4-rc1
Git-commit: a643c6de1441e5cdab88452c46fe7c38b318009e
References: jsc#SLE-8284 jsc#SLE-8654
If admin changes the devloss_tmo on an rport via the fc_remote_port rport
dev_loss_tmo attribute, the value is on set on scsi stack. The change is
not propagated to NVMe.
The set routine in the lldd lacks the call to
nvme_fc_set_remoteport_devloss() to set the value.
Fix by adding the call to the lldd set routine.
