[SCSI] libfc: Check if exchange is completed when receiving a sequence

When a sequence is received in response to an exchange we issued previously,
we should check to see if the exchange has completed. If yes, the sequence
should be discarded. Since the exchange might be still in the completion
process, it should be untouched.
