ort FC_ID is being assigned.  It defaults to
fc_lport_set_fid(), supplied by libfc.

As additional benefit of this function, the LLD may determine
the MAC address that caused the change by looking at the received frame.

We also print the assigned port ID as long as it isn't 0.
Setting port ID to 0 happens often in reset while retrying FLOGI,
and would be uninteresting.  This replaces the previous message
which didn't identify the host adapter instance.

patch v2 note: changed one word in a comment.  "intercepted" -> "provided".
