AP: Fix 6 GHz AP setup after disable-enable

Browse source 
Once ACS picks a channel, iface->freq and iface->conf->channel are
updated. So, AP comes up in the last operating channel when 'ENABLED'
after 'DISABLED' though ACS is configured.

But this will fail for 6 GHz APs since configured_fixed_chan_to_freq()
checks if iface->conf->channel is filled or not irrespective of ACS
configuration, and the checks inside configured_fixed_chan_to_freq()
fail the AP setup. Fix this by clearing iface->freq and
iface->conf->channel in AP setup for ACS configuration.

Fixes: bb781c763f ("AP: Populate iface->freq before starting AP")
