Sometimes we hit a race on hot-plug where we try to read the KMS resources and the EDID blob is not yet ready. This would normally result in a ENOENT when retrieving the blob. Handle this by retrying after 50 milliseconds after a hot-plug event. Do this up to 10 times, and after that give up trying to get the EDID blob and continue with best effort. https://bugzilla.gnome.org/show_bug.cgi?id=777732
