Imre Deak c3bad0c7e5 drm/i915: Fix the old vs. new epoch counter check during hotplug detect
The old epoch counter was left uninited, so the function returned a
changed state always.

While at it debug print the old epoch counter as well.

Fixes: 35205ee9ba ("drm/i915: Send hotplug event if edid had changed")
