monitor-config-manager: Fix 90/270 degree rotation not working

Browse Source 
When rotating 90/270 degrees we need to swap width and height. This fixes
the screen going black and the following errors showing in the journal:

gnome-shell[1097]: Failed to set CRTC mode 800x1280: No space left on device
gnome-shell[1097]: Failed to flip: Device or resource busy
gnome-shell[1097]: Failed to set CRTC mode 800x1280: No space left on device
gnome-shell[1097]: Failed to set CRTC mode 800x1280: No space left on device

When rotating a tablet with accelerometer 90/270 degrees.
