brcmfmac: use control channel in roamed status reporting
Channel reported in scan results passed to cfg80211 is control channel. But chanspec is reported while notifying cfg80211 about roamed update. Cfg80211 complains because it could not find the bss in the list. Report control channel while calling cfg80211_roamed. Signed-off-by: Franky Lin <frankyl@broadcom.com> Signed-off-by: John W.
