Should have actually tested this with full group formation before
applying.. The added "break;" there removes ap_mgmt_rx() calls and
prevents Probe Request frame processing in GO. This results in failed
group formation with mac80211_hwsim (and well, any driver that handle
Probe Request frames in user space). It looks like removing that break
is enough to fix this.
