ide: pass error value to ide_complete_rq()
Set rq->errors at ide_complete_rq() call sites and then pass error value to ide_complete_rq(). [ Some rq->errors assignments look really wrong but this patch leaves them alone to not introduce too many changes at once. ] There should be no functional changes caused by this patch.
