Fix sporadic issue in test.

- Parse commands after flush
- Sequence was as follows:
ndr1
1.Parse commands
ndr2
2.Parse commands

cmdq->flush
cmdq2->flush

During parsing #1 we parse BATCH_BUFFER_END at the end of command buffer.
Following NOOP is also parsed.

Then at flush time, BATCH_BUFFER_END is replace with BATCH_BUFFER_START
as we chain them together, however parser is not updated at this point
and still thinks that there is BATCH_BUFFER_END there.

Then we try to locate MEDIA_VFE_STATE, under NOOP iterator we currently
have BATCH_BUFFER_START GPU VA start address that is random.
Depending on the luck, address may be interpreted as VFE_STATE and
test sporadically fails :)
