    Don't unnecessarily loop through all ports/interfaces

    The ovs-vsctl 'list' command can take a list of records as an
    argument, so there is no need to manually loop through all records
    discarding the ones with names that don't match the bridge's
    port name list.

    Also, since the data is returned as json, the ofport returned isn't
    a string, so we don't have to convert it to int for testing.
