clock: Don't forward management requests to UDS port.
The UDS port is not expected to be used by PTP clocks and forwarding of management messages to the port can be limited to responses. This prevents ptp4l from printing error messages when a management request is received from a non-UDS port and the last client which used the UDS port is no longer listening.
