[SCSI] libfc: don't require a local exchange for incoming requests
Incoming requests shouldn't require a local exchange if we're just going to reply with one or two frames and don't expect anything further. Don't allocate exchanges for such requests until requested by the upper-layer protocol. The sequence is always NULL for new requests, so remove that as an argument to request handlers. Also change the first argument to lport->tt.seq_els_rsp_send from the sequence pointer to the received frame pointer, to supply the exchange IDs and destination ID info.
