BSSAP: Fix test_codec_pref() implementation for AMR

In AMR-type cahnels, the gsm0808_speech_codec doesn't only include
the codec (like EFR/FR/AMR) but also the specific codec configuration,
i.e. the sub-set of AMR modes.

Hence, we cannot convert from a channel type (just the codec) to the
full gsm0808_speech_codec and then memcmp() that with the codec config
received from the MSC.  Rather, we must only compare the *type*.
