SF: Requery display modes if the active mode is not supported
Some TV devices send two hotplug events immediately one after another
during startup. Because we query the active display mode
and the supported modes in two separete calls to HWC it's possible
to get an active mode, which is not in the list of supported modes.
If this happens we requery the display modes up to 3 times. If the
problem still persists we throw a fatal error.
