mi: only call UpdateSpriteForScreen if the screen actually changed.

Browse Source 
If we call it unconditionally, we flip the dev->spriteInfo->sprite permanently
when using XTestFakeInput (once in CheckMotion as called from the
processInputProc, another time in UpdateSpriteForScreen when we actually warp
the cursor). USFS also updates to the screen's root window unconditionally,
which is not really what we want if we haven't changed screen at all.
