mac80211: let flush() drop packets when possible
When roaming / suspending, it makes no sense to wait until the transmit queues of the device are empty. In extreme condition they can be starved (VO saturating the air), but even in regular cases, it is pointless to delay the roaming because the low level driver is trying to send packets to an AP which is far away. We'd rather drop these packets and let TCP retransmit if needed. This will allow to speed up the roaming. For suspend, the explanation is even more trivial.
