From: Avraham Stern <avraham.stern@xxxxxxxxx>
MLO internal scan may include 6 GHz channels. Since the 6 GHz scan
indication is not set, the channel flags are set incorrectly, which
leads to a firmware assert.
Since the MLO scan may include 6 GHz and non 6 GHz channels in one
request, add support for non-PSC 6 GHz channels (PSC channels are
already supported) when the 6 GHz indication is not set.
