gdkwindow: Do not rely on a previous slave device when updating grab

Browse Source 
_gdk_display_device_grab_update does not support passing in NULL for the
source device. If we don't have a slave device (saved in the pointer info)
then do not try and use that NULL pointer for the source_device.

This bug appeared in the Wayland backend where we (currently) only have master
devices exposed and as such no slave device is ever saved.
