From: Johannes Berg <johannes.berg@xxxxxxxxx> When any interface goes down, it could be the one that we were doing off-channel with. Thus, we need to flush the offchannel start/stop work so they can't run when the interface has already been removed from the driver or even been destroyed. It's OK to flush them even if they were for another interface, that just means that we potentially delay the interface down a little bit.
