dpp-nfc: Use --altchan value in handover server

Browse source 
Use the alternative channel list in the handover server role when
processing an alternative proposal. This was previously done only in the
handover client role, but with the updated design, both roles act in a
similar manner for the case where the alternative channel list is
specified.
