vlan: q-in-q: T1551: add missing if statement to check if vlan interface exists
When adding the interface and getting a commit error e.g. due to missing firewall
this resulted in an additional error when committing again after adding the
missing firewall rule.
This can be fixed by only creating the outer vif-s interface if it yet does not
exist.
