mac80211: mesh: don't use global channel type
Using local->_oper_channel_type in the mesh code is completely wrong as this value is the combination of the various interface channel types and can be a different value from the mesh interface in case there are multiple virtual interfaces. Use sdata->vif.bss_conf.channel_type instead as it tracks the per-vif channel type. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
