Subject: [PATCH iproute2] bridge: vlan json: skip ports with empty vlans

From: Roopa Prabhu <roopa@...ulusnetworks.com>

The non-json output prints 'None' for such vlans.
And this can garble json output.

Fixes: d82a49ce85f0 ("bridge: add json support for bridge vlan show")

saw this when deploying a mix of vlan filtering and non-vlan
