Scan failure can not be recovered from when running a loop of the
following steps:
1. run scan: "iw wlan scan".
2. run command: echo assert > /sys/kernel/debug/ath12k/wcn7850\ hw2.0/simulate_fw_crash
   immediately after step 1.

result:
scan failed and can not recover even when wlan recovery succeeds:
command failed: Device or resource busy (-16)

reason:
When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and
function ath12k_mac_op_hw_scan() returns, then simulate_fw_crash arrives
and the scan started event does not arrive, and then it starts to do
recovery of wlan. __ath12k_mac_scan_finish() which is called from
ath12k_core_halt() is one step of recovery, it will not call
ieee80211_scan_completed() by logic currently because the scan state is
ATH12K_SCAN_STARTING. Thus it leads the scan not being completed in
mac80211, and leads all consecutive scans failing with -EBUSY in
nl80211_trigger_scan even after wlan recovery success.

Indicate scan complete with aborted flag to mac80211 for
ATH12K_SCAN_STARTING to allow recovery from scan failed with "Device or
resource busy (-16)" after wlan recovery.
