mac80211: mesh: mark channel as unusable if a regulatory MESH CSA is received
In the Mesh Channel Switch Parameters (8.4.2.105) the reason is specified
to WLAN_REASON_MESH_CHAN_REGULATORY in the case that a regulatory
limitation was the cause for the switch. This means another station
detected a radar event.
Mark the channel as unusable if this happens.
