Currently when the MS does a re-attach without doing a proper detach first, the gbproxy uses the old local TLLI if patching and the keep mode are enabled. This leads to a failing attachment procedure when TLLI patching is also enabled. This patch changes gbproxy_update_link_state_ul to reset all TLLIs within the link_info if the message contains an unknown TLLI and an MI. This is generally the case with Attach Request messages. The gbproxy_get_link_info_ul gets an additional tlli_is_valid output parameter that is set, when a TLLI was present and found. This flag is then used instead of checking tlli.current == 0 to set TLLI/P-TMSI e.g. Attach Requests when a link_info was already present for the P-TMSI/IMSI used in such a request.
