[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.
