MT Calls: Copy bearer capabilities from NNCC primitive to trans 

When we receive a MNCC_SETUP_REQ primitive from the external MNCC
handler, we must not only encode it into the TS 04.08 CC SETUP, but
also keep it around in the "trans" structure representing this voice
call, as it is needed e.g. at BSSMAP ASSIGNMENT time.
