REQ_OP_FLUSH appears in the submission path processing but not in
the response path processing. Hence it takes the "default" case
which seems to be designed for REQ_OP_READ and REQ_OP_WRITE.
So add a REQ_OP_FLUSH case to the response path.

Is it correct to treat REQ_OP_FLUSH like the other OPs that
may send but never return data (as in a READ's data-in)?
Should this be fixed separately in the mainline?
