brcm80211: smac: always set channel specified by mac80211

Browse Source 
In some situations brcmsmac is choosing a channel internally. This makes
it difficult at times to know what channel to use for enforcing
regulatory constraints, so instead always use the channel from the
mac80211 configuration.
