scsi: lpfc: Fix multiple NVMe remoteport registration calls for the same NPort ID

Browse source

When a target makes the mistake of registering a FC4 type with the fabric,
but then rejects a PRLI of that type, the lpfc driver incorrectly retries
the PRLI causing multiple registrations with the transport. The driver
needs to detect the reject reason data and stop any retry.

Rework the PRLI reject scenarios.
