Staging: batman-adv: Fix VIS output bug for secondary interfaces

commit f6497e38fda6970819daacb67725d67474079381 upstream.

TQ and HNA records for originators on secondary interfaces were
wrongly being included on the primary interface. Ensure we output a
line for each source interface on every node, so we correctly separate
primary and secondary interface records.
