[gssdp] Use int consistently for packet info interface index

[Jens Georg <jensgeorg src gnome org>]

commit 21a9e99b55f19c492a3a09dac831efe2879dee99
Author: Jussi Kukkonen <jku goto fi>

    Use int consistently for packet info interface index
    
    g_value_set_uint() with an int argument is not good: use int consistently
    (based on the kernel value being an int).
