Screen size bounds check in ProcRRSetCrtcConfig not masking out reflections.

Browse Source 
When checking how to validate the selected mode and position against the
current screen size, the test against 90/270 rotation did not mask out
reflection, so that when reflection was specified, the 90/270 test would
never succeed. This caused incorrect bounds checking and would return
an error to the user instead of rotating the screen.
