randr: Fix crtc_bounds when using rotation combined with reflection 

Before this commit crtc_bounds() did not take reflection into account,
when using reflection with 0 / 180 degree rotation this was not an
issue because of the default in the switch-case doing the right thing.

But when using 90 / 270 degree rotation we would also end up in the
default which is wrong in this case. This would lead to the cursor
being constrained to a height x height area of the monitor.

This commit masks out the reflection bits for the switch-case,
making crtc_bounds return the correct bounds and fixing the
problematic cursor constraining.
