ath10k: report estimated frame transmit airtime to improve fairness
The airtime of a transmitted frame will be estimated from last used tx rate
which the firmware reports with the peer stats feature
(WMI_SERVICE_PEER_STATS). The airtime is computed on the tx path and it
will be reported to mac80211 upon tx completion.
This change is based on Kan's orginal commit in Chromium tree
("CHROMIUM: ath10k: Implementing airtime fairness based TX scheduler")
ref: https://chromium-review.googlesource.com/588190
Tested on QCA4019 with firmware version 10.4-3.2.1.1-00015
Tested on QCA9984 with firmware version 10.4-3.9.0.1-00005
