Before a reset, we set the STOP_RING bit of RING_MI_MODE to freeze the
engine. However, sometimes we observe that upon restart, the engine
freezes again with the STOP_RING bit still asserted. By inspection, we
know that the register itself is cleared by the GPU reset, so that bit
must be preserved inside the context image and reloaded from there. A
simple fix (as the RING_MI_MODE is at a fixed offset in a valid context)
is to clobber the STOP_RING bit inside the image before replaying the
request.

When resetting the context image after a GPU reset, it is vital that we
do inspect the context image that was active at the time of the hang.
Even a 'pardoned' context may still have some residual corruption (e.g.
the STOP_RING bit) from issuing the GPU reset that we need to fixup
before continuing.
