MFC r313414:

[iwm] Use iwm_mvm_scan_stop_wait to properly abort scans.

* Add IWM_FLAG_SCAN_RUNNING to sc->sc_flags to track whether the firmware
  is currently running a scan, in order to decide wheter iwm_scan_end
  needs to abort a running scan.

* In iwm_scan_end, if the scan is still running, we now abort it, in order
  to keep the firmware scanning state in sync.

* Try to make things a bit simpler, by reacting on the
  IWM_SCAN_OFFLOAD_COMPLETE and IWM_SCAN_COMPLETE_UMAC notifications,
  instead of IWM_SCAN_ITERATION_COMPLETE and
  IWM_SCAN_ITERATION_COMPLETE_UMAC. This should be fine since we always
  only tell the firmware to do a single scan iteration anyway.
