[mutter] xprops: Free meta_prop_get_cardinal_list() return value with g_free()

[Jonas Ådahl <jadahl src gnome org>]

commit 5eaf6552240dd7d7a48705c2fe665a772926bbbb

    xprops: Free meta_prop_get_cardinal_list() return value with g_free()
    
    meta_prop_get_cardinal_list directly passes through the results->prop
    pointer which is g_malloc memory, so we should free the buffer it
    returns with g_free.
