scsi: lpfc: Update various NPIV diagnostic log messaging

Update PRLI status log message to automatically warn when CQE status is
non-zero.

When issuing an RSCN, log ndlp's kref count to the debugfs trace buffer.

Add the NPIV virtual port index to the FDMI registration log message
with the fabric.
