hostapd: fix a race condition on adding AP mode wds sta interfaces Both hostapd and netifd attempt to add a VLAN device to a bridge. Depending on which one wins the race, bridge vlan settings might be incomplete, or hostapd might run into an error and refuse to service the client. Fix this by preventing hostapd from adding interfaces to the bridge and instead rely entirely on netifd handling this properly Signed-off-by: Felix Fietkau <nbd@nbd.name> (cherry-picked from commit da4be02fcd5d642954b1c9d9855d9e8d1e6205f4) (cherry-picked from commit 63c01ad025981eaa841353dc0fc27e5017febe21)
