[PATCH xf86-video-ati] Wrap the whole miPointerScreenFuncRec, instead of only Set/MoveCursor
Michel Dänzer

From: Michel Dänzer <michel.daenzer at amd.com>
We were clobbering entries in mi's global miSpritePointerFuncs struct,
which cannot work correctly with multiple primary screens. Instead,
assign a pointer to our own wrapper struct to PointPriv->spriteFuncs.
Fixes crashes with multiple primary screens.
Fixes: 1fe8ca75974c ("Keep track of how many SW cursors are visible on
each screen")
