gsm48_cc_tx_setup: fix speech bearer capabilities
Send the bearer capability IE from 3GPP TS 24.008 § D.1.2 for speech
instead of the result from gsm48_cc_tx_setup_set_bearer_cap() for the
network to MS direction. This is needed, because:
- We shall send spare bits for the radio channel requirement in the
network to MS direction, see 3GPP TS 24.008 § D.1.1 and Table
10.5.102).
- We could in theory send a speech version list that MS are then
supposed to ignore (end of Table 10.5.103), but this causes bugs in
some MS so it is better to not send it (OS#6656).
