[SCSI] libfc: Add local port point-to-multipoint flag
For VN_port to VN_port mode, the transport sets the port_id and there's no lport FLOGI. This is similar to FC loop mode. Add a point_to_multipoint flag that indicates the local port is in point-to-multipoint mode. This skips FLOGI and discovery. It also skips resetting the port_id on resets other than link down. Add function fc_lport_set_local_id() that sets the local port_id. This is called by libfcoe on behalf of the low-level driver to set the port_id when the link comes up.
