wlb: T9472: report the initial state of every interface

On start the health daemon forces a state change so the hook learns the
initial state of the WAN interfaces. The flag doing so was reset after the
first interface, every other interface was only reported once its state
actually changed.

The flag is now reset after all interfaces have been checked. The existing
hook smoketest relied on the old behaviour: it now keeps all hook events
and no longer reads a file left over from an earlier run.
