[FS#1341] vlan configuration fails

[LEDE Bugs]

The following task has a new comment added:

FS#1341 - vlan configuration fails
User who did this - Routing Route (rrt)

----------
I found other vlan issues that I think could be other symptoms of lede trying to configure the vlans with a half-working swconfig sequence (only works if counter equals vlan id?)

I left comments on the other issues, but maybe the syntax/sequence mismatch reported in this issue is the root cause.
