db: Resolve SAWarning warnings

Resolve the following SAWarning warning:

  SELECT statement has a cartesian product between FROM element(s)
  "foo" and FROM element "bar". Apply join condition(s) between each
  element to resolve.

This was happening because we were filtering instances of
ConductorHardwareInterfaces by the state of the Conductor referenced by
the 'conductor_id' field *without* joining the Conductor table. By
adding the join, we can avoid this cartesian product.
