Remove the return value of setDeviceCoordinateSystem

In https://skia-review.googlesource.com/c/skia/+/527505 we removed the
'invert' call from 'SetDeviceCoordinateSystem', removing the only place
where the function might return 'false'. This patch changes the return
value from bool to void, as it is obsolete.
