From: Benjamin Berg <benjamin.berg@xxxxxxxxx>
Previously, we would only pass the event to the first interface that
matches. However, one wiphy can have multiple interfaces and each one
needs to get the event delivered. Without this, it could e.g. happen
that a radar detection event is forwarded to p2p-dev-wlan0 and not to
the wlan0 interface which actually needs it.
As such, keep iterating if we are processing a wiphy match and send the
event to all affected BSSs.
