tbf/bts, encoding: Keep track of WAIT_RELEASE state for DL assignment
The current code does not properly distinguish between DL assignments to reuse a tbf (after it was put in state WAIT_RELEASE) and DL assignments for an active tbf to change the allocation of the PDCH timeslots. This patch introduces a new variable was_releasing which remembers if trigger_dl_ass() was called with a tbf in state WAIT_RELEASE. In that case we have to set the CONTROL_ACK field in the download assignment. This should allow us to send DL assignments to change PDCH TS allocation of a tbf before we enter FLOW state.
