wifi: ath12k: flush all packets before suspend

Browse source

In order to send out all packets before going to suspend, current code
adds a 500ms delay as a workaround. It is a rough estimate and may not
work.

Fix this by checking packet counters, if counters become zero, then all
packets are sent out or dropped.
