The firmware will cancel the current scan after receiving WMI_SCAN_CHAN_LIST_CMDID which is used for the new channel list, and the state of ath11k is ATH11K_SCAN_RUNNING, then ath11k_get_ar_on_scan_abort() returns NULL and ath11k_scan_event() returns at this point and does not indicate scan completion to mac80211. Indicate scan completion to mac80211 and get rid of the "Received scan event for unknown vdev" print for the above case.
