Subject: [PATCH 4/7] mesh: do not set offchanok on DFS channels in non-ETSI
mac80211 does not allow mgmt tx to use off channel on
DFS channels in non-ETSI domain, because it will invalidate
CAC result on current operating channel.
(mac80211 commit: 34373d12f3cbb74960a73431138ef619d857996f)
Hence don't set offchanok for mgmt tx in case of DFS channels
in non-ETSI.
