issue: under SR-IOV sometimes the iB test will fail on gfx ring fix: with cond_exec inserted in RB the gfx engine would skip part packets if RLCV issue PREEMPT on gfx engine if gfx engine is prior to COND_EXEC packet, this is okay for regular command from UMD, but for the ib test since the whole dma format doesn't support PREEMPT so must remove the COND_EXEC from it.
