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.
