scsi: lpfc: Fix driver nvme rescan logging
In situations where zoning is not being used, thus NVMe initiators see
other NVMe initiators as well as NVMe targets, a link bounce on an
initiator will cause the NVMe initiators to spew "6169" State Error
messages.
The driver is not qualifying whether the remote port is a NVMe targer or
not before calling the lpfc_nvme_rescan_port(), which validates the role
and prints the message if its only an NVMe initiator.
Fix by the following:
- Before calling lpfc_nvme_rescan_port() ensure that the node is a NVMe
storage target or a NVMe discovery controller.
- Clean up implementation of lpfc_nvme_rescan_port. remoteport pointer
will always be NULL if a NVMe initiator only. But, grabbing of
remoteport pointer should be done under lock to coincide with the
registering of the remote port with the fc transport.
