The recently added phc2sys multi-domain mode introduced a regression. In the non-automatic mode (using flag -w to wait for ptp4l) the code will attempt to set the UDS address using an uninitialized pointer, unless the -z flag is also specified.
Fix the issue by testing whether the -z flag was present on the command line before changing the UDS address.
