From: Benjamin Berg <benjamin.berg@intel.com>

The driver debugfs entries still exist when the interface is re-added
during reconfiguration. This can be either because of a HW restart
(in_reconfig) or because we are resuming.

Fixes: a1f5dcb1c0c1 ("wifi: mac80211: add a driver callback to add vif debugfs")
