[PATCH] libosmo-netif[releases/0.0.6-stable]: osmux: Add function to delete all msgs pending for a circuit

[Holger Freyther]

Hello Jenkins Builder,

I'd like you to do a code review.  Please visit

    https://gerrit.osmocom.org/122

to review the following change.

osmux: Add function to delete all msgs pending for a circuit

Use this function in osmux_batch_del_circuit() since msgs are stored in a list
per circuit. After the circuit is free()d the msgs are lost.
Before this patch any messages enqueued inside a batch when the circiut is
deleted were leaking.
