Lucas Stach 7a9c0fe20e drm/etnaviv: use submit exec_state for perfmon sampling
The GPU exec state may have changed at the time when the perfmon sampling
is done, as it reflects the state of the last submission, not the current
GPU execution state.

So for proper sampling we must use the submit exec_state.
