drm/i915: Keep userpointer bindings if seqcount is unchanged, v2.
Instead of force unbinding and rebinding every time, we try to check
if our notifier seqcount is still correct when pages are bound. This
way we only rebind userptr when we need to, and prevent stalls.
Changes since v1:
- Missing mutex_unlock, reported by kbuild.
