xfree86/modes: Take rotation into account when checking mode size 

Assume that a mode can be used in either landscape or portrait
orientation. I suppose the correct thing to do would be to
collect all the supported rotations from the CRTCs that can be used
with a specific output, but that information doesn't seem to be
readily available when these checks are done. So just assume that
either orientation is fine.
