ath10k: improve tx status reporting
We use ieee80211_tx_status() to report each completed tx frame.
Internally, this function calls sta_info_get_by_addrs(), what has a
couple of drawbacks:
1. additional station lookup causes a performance degradation;
2. mac80211 can not properly account Ethernet encapsulated frames due
to the inability to properly determine the destination (station) MAC
address since ieee80211_tx_status() assumes the frame has a 802.11
header.
The latter is especially destructive if we want to use hardware frames
encapsulation.
To fix both of these issues, replace ieee80211_tx_status() with
ieee80211_tx_status_ext() call and feed it station pointer from the tx
queue associated with the transmitted frame.
