core: ordered chapters: fix bad subtitle parameter

mp_property_do() takes the value to set a property to through a
pointer. The calling code used '&mpctx->global_sub_pos' as the
pointer; however that variable could be changed during the
mp_property_do() call. Use a pointer to a copy of the original value
instead.

I think this only caused problems if you switched subtitle tracks from
a real one to "disabled" and then switched to a timeline part from
another source.
