ploop: remove preflush from dio_submit
After commit c2247f3745 fixing barriers for ordinary
requests and previous patch fixing delay_fua,
that legacy code in dio_submit processing
(preq->req_rw & REQ_FLUSH) by setting REQ_FLUSH in
the first outgoing bio must die: it is incorrect
anyway (we don't wait for completion of the first
bio before sending others).
