gprs_llc: Work on finding the right LLE/LLME in case of routing area update

Attempt to solve what f0901f0067e363c0ced6254db1b45a9771640412 tried to
solve without breaking the case of someone with a foreign TLLI from a
different network.

Lookup with the foreign TLLI converted to a local one in case we did
not find the TLLI and only then create a LLE/LLME on the fly for the
RX path.
