xwayland: call through to miPointerWarpCursor on warp_cursor 

This is (eventually) called during
InitializeSprite() → *pScreen->SetCursorPosition → miPointerSetCursorPosition
when a device is set to floating. We don't do anything special outselves, but
we need to pass on to the next layer to make sure the device is initialized
properly. Otherwise, pScreen stays NULL and eventually crashes the server when
we try to clean up behind us.

Test case: grab a device → floats it, ungrab again → crash
