drm/i915: Always stop the rings before a missing GPU reset
Always try to stop the rings, even if the GPU reset itself has been
disabled (via modparam i915.reset). This should at least stop the hw
from spinning in the background consuming resources (e.g. power and
memory bandwidth) letting the system rest-in-peace.

drm/i915: Keep the rings stopped until they have been re-initialized
Before modifying the ring register (RING_START, HEAD, TAIL, CTL) we
first make sure it is stopped (or else the hw may not resample the
registers). However, we do not need to let the hw restart until after we
have reprogrammed all the rings. This should help prevent situations
where pending operations on the ring may resume (because we are trying
to re-initialize following an unsuccessful GPU hang, i.e. from
i915_gem_unset_wedged).
