codec_pref: check bts codec support

The vty option bts->codec-support allows the user to set the supported
codecs per BTS level. However, those values are currently only used to
make the handover decision but the logic that handles the BSSMAP
ASSIGNMENT REQUEST does not check those flags.

- Do not ignore bts->codec-support flags on BSSMAP ASSIGNMENT REQUEST
