[SGSN] Fix processing of RA Update Request regarding TLLI
In case we get a RA UPD REQ on a new cell (both served by the same
SGSN), the LLC stack should not allocate a ne LLE/LLME, as the latter
would reset the V(u)sent / V(u)recv to zero and make the MS discard
our responses.
Instead, whenever the LLC stack sees a foreign TLLI, it should always
convert it to the local TLLI before doing any lookup for a LLE/LLME.
