When a VLAN is added to a bridge port, a master VLAN gets created on the
bridge for context, but it doesn't have the BRENTRY flag.
Then, when the same VLAN is added to the bridge itself, that enters
through the br_vlan_add_existing() code path and gains the BRENTRY flag,
thus it becomes "existing".
It seems natural to check for this condition early, because the current
code flow is to notify switchdev of the addition of a VLAN that isn't a
brentry, just to delete it immediately afterwards.
