gsm_08_08: allow zero length speech codec lists in compl l3 info.
The COMPLETE LAYER 3 INFORMATION message contains a an Codec List (BSS Supported). When generating the compl l3 info msg, we check if the speech codec list that we have generated before has at least one element. If it has 0 elements we abort immediately. However, speech codec lists with 0 elements are permitted by the spec, so we should remove the checks as there are corner cases where voice support is intentionally unavailable. - Remove check for zero length speech codec lists.
