nl80211: Fix tearing down WDS STA interfaces

wpa_driver_nl80211_if_remove() checks bss->if_added before deleting an
interface, which is 0 for the first BSS. The only part of
wpa_driver_nl80211_if_remove() that should get called for WDS STA
interfaces is the call to nl80211_remove_iface(), which can be pulled in
here directly.
