libbsc: Release the RF channel if BTS thinks it's still in use
The Nokia metrosite BTS seem to keep the channels open indefinitely. If osmo-nitb is restarted while one of the channel was still active and tries to activate that channel again the bts would return a CHANNEL ACTIVATE NACK with "Radio channel already activated". This accumulated over the restarts so soon enough no more channels were available. This patch sends a release request to the bts so the channel becomes available again.
