[ Upstream commit 1bf66dc31032ff5292f4d5b76436653f269fcfbd ]
We should reset mstat->airtime_ac along with clear up the entries in the hardware WLAN table for the Rx and Rx accumulative airtime. Otherwsie, the value msta->airtime_ac - [tx, rx]_last may be a negative and that is not the actual airtime the device took in the last run.
