iwlwifi: mvm: add UMAC scan iteration complete notification
Add UMAC scan iteration complete notification. This notification can
be enabled by setting scan_iter_notif_enabled through debugfs.
Upon receiving this notification, print the list of channels that
have been scanned in this iteration. This is useful for debugging.
