The ath9k driver was not properly clearing the status area in the
ieee80211_tx_info struct before reporting TX status to mac80211. Instead,
it was manually filling in fields, which meant that fields introduced later
were left as-is.
Conveniently, mac80211 actually provides a helper to zero out the status
area, so use that to make sure we zero everything.
The last commit touching the driver function writing the status information
seems to have actually been fixing an issue that was also caused by the
area being uninitialised; but it only added clearing of a single field
instead of the whole struct. That is now redundant, though, so revert that
commit and use it as a convenient Fixes tag.

However, there is something missing. I don't see Cc: stable@xxxxxxxxxxxxxxx
trailer in this patch. I think it should, because I reported that this issue
first occurred on v5.17, then still appeared on v5.17.1.
