  - Merge "Search for active port binding when updating LSP host info"
  - Search for active port binding when updating LSP host info

    When updating LSP host info for an UP port, the code
    always uses the first port binding in the DB entry
    (db_port.port_bindings[0].host).

    Since there could be multiple port bindings present,
    search for the active one when determining which host
    value to use.
