2 WAN on a single port

[psherman]

I just noticed a minor error...

@psherman

config bridge-vlan
        option device 'br-lan'
        option vlan '1'
        list ports 'lan1'
        list ports 'lan2'
        list ports 'wan:t'

Remove ports lan1 and lan2 from VLAN 1. It should only be tagged on wan like this:

config bridge-vlan
        option device 'br-lan'
        option vlan '1'
        list ports 'wan:t'
