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.
