Revert "osmo-bts-trx: rx_tchf_fn(): do not treat AFS_SID_UPDATE as SUB frame"
This reverts commit 1f9fbd881602f20f5d83b94f2332c18c19b680e0, which
was a workaround rather than a proper fix. The root problem has
been fixed in libosmocoding [1], so ~50% BER is not the case for
AFS_SID_UPDATE frames anymore.
