Tests _must_ be able to run as non-root and on non-intel platforms,
otherwise the enumeration is busted (since QA enumerates testcases on
a gpu-less xeon box).

If we stop all the rings, we can end up blaming the innocent
rings on hangcheck.

Use own copy of gem_quiescent_gpu() so that test still works
if it gets changed. Further improve the test by posting a batch
to rings in reverse order.

This triggers use after free oops on request->batch_obj when
going through the rings and setting reset status on requests,
after a gpu hang.

For BDW+, there BATCH_BUFFER_START is 3 * 32bits in length and
length needs to be encoded into the opcode.

Instead of freaking out about negating the skip condition and punting
I could have remembered that I've solved this already ...
