From: Andrei Otcheretianski <andrei.otcheretianski@intel.com>

If a frame is dropped for any reason, mac80211 wouldn't report the TX
status back to user space.

As the user space may rely on the TX_STATUS to kick its state
machines, resends etc, it's better to just report this frame as not
acked instead.
