commit e513ae49088bbb0d00299a9f996f88f08cca7dc6 upstream.
Scan abort should be required for the uncompleted hardware scan interrupted by wifi reset. Otherwise, it is possible that the scan request after wifi reset gets error code -EBUSY from mac80211 and then blocks the reconnectting to the access point.
