BTS indicates "Unlocked" state of Radio Carrier on connect
One of the first messages osmo-bts is sending on OML is the "State Changed Event Report" for the "Radio Carrier". Unfortunately the message states "Administrative State: Unlocked", which should not be the case. The object should come up in "locked" state until it's explicitly unlocked by the BSC.
See Section 6.8.2 of TS 12.21: "If there is yet no administrative state value explicitly set by
the BSC (e.g., at an initialization time), the object shall be presumed to be administratively locked by default"
