[PATCH 03/21] lpfc: Fix loop mode target discovery

The driver does not discover targets when in loop mode.

The NLP type is correctly getting set when a fabric connection is
detected but, not for loop. The unknown NLP type means that the
driver does not issue a PRLI when in loop topology. Thus target
discovery fails.

Fix by checking the topology during discovery. If it is loop,
set the NLP FC4 type to FCP.
