commit 9ea0c307609fd20e03f53546b9cefbb20b96785d upstream.

During init we take care of regulatory stuff by disabling all unavailable channels (see brcmf_construct_chaninfo) so this predisabling them is not really required (and this patch won't change any behavior). It will on the other hand allow more detailed runtime control over channels which is the main reason for this change.
