Peter Hutterer 0478a33d18 mi: guard miPointer functions against NULL dereferences 
Already in place for some functions, let's add it to most others.
The only function missing is miPointerSetPosition() which needs to
return the ScreenPtr and that one is unclear if we don't have a screen -
returning NULL will crash the caller(s) so let's wait for something to
trigger this bug before we try to fix it wrongly.
