dix, mi: stop segfaults when a floating device emits events.
For pointers: don't try to set master->valuator fields if there is no master. For keyboards: check if device is valid before trying to access the fields in miPointerGetScreen (btw. this disables DGA events for floating keyboards). Also stop the hideous number of ErrorFs if we request the paired device for a floating dev.
