    drm/i915/execlists: Mark up expected state during reset

    Move the BUG_ON around slightly and add some explanations for each to
    try and capture the expected state more carefully. We want to compare
    the expected active state of our bookkeeping as compared to the tracked
    HW state.

makes the BUG_ON go away. Doesn't answer how we got into that state, but maybe
that will go away all by itself.
