tbf: Get the TLLI from the MS object

Since the synchronisation of the TBF's concerning the TLLIs has been
removed in 'Support new and old TLLI's', gprs_rlcmac_tbf::tlli() can
return the old TLLI which is probably different to ms()->tlli() in
that case. This can lead to a wrong TLLI being used in BSSGP messages.

This commit modifies the TBF's tlli() method to get the current TLLI
from the MS object.
