[PATCH] openbsc[master]: lchan: Release channel in case of late activation ack

[Holger Freyther]

lchan: Release channel in case of late activation ack

In case of the sysmoBTS and receiving a channel activation ack on
a channel that was marked as broken, release it again.

Use a normal release without SACCH deactivation and release the
rqd_ta data.
