xf86_crtc_rotate_coord_back should be the exact inverse operation of
xf86_crtc_rotate_coord, but when calculating x / y for 90 / 270 degrees
rotation it was using height to calculate x / width to calculate y,
instead of the otherway around.
This was likely not noticed before since xf86_crtc_rotate_coord_back
until now was only used with cursor_info->MaxWidth and
cursor_info->MaxHeight, which are usally the same.
