[S] Change in osmo-bts[master]: cosmetic: Remove "FIXME?" from Odd AMR CMI phase

laforge has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bts/+/32108 ) Change subject: cosmetic: Remove "FIXME?" from Odd AMR CMI phase ...................................................................... cosmetic: Remove "FIXME?" from Odd AMR CMI phase This default phase of the Codec Mode Indication in downlink direction is called "odd", which is defined by starting with CMC in every 26 multiframe. At call set-up, after every successful handover and after a channel mode modify, the default phase (odd) shall be used in downlink direction. During a call, the phase of Codec Mode Indication may be changed in downlink by using a RATSCCH message. As we don't implement RATSCCH, odd is always correct.
