[SCSI] libfcoe: FIP link keep-alive should continue while logged off

A check in fcoe_ctlr_send_keep_alive() returns if there's no
port_id for the local port.  This could miss a keep alive if
we just did a host reset and have logged off and will log back in.

Return only if we are doing the port keep alive, in which case
we need to be logged in.
