cursor-renderer-native: Don't use HW cursor on transformed logical monitor

Browse Source 
The HW cursor plane can't do any transformations, and as we still don't
pre-transform any buffer before uploading to the cursor plane, we must
disable the HW cursor when a logical monitor is transformed.

This worked previously because the transform of a MetaCrtc did not
correspond to the transform of a CRTC, but the transform of the logical
monitor the CRTC was assigned to.
