update breakout function so that it doesn't inherit remote port structure

The NIC Breakout function creates a set of sub-ports for the NIC that connect to the slice of destination ports passed to the function. Currently, it copies the remote port configuration onto the new ports that are created. I don't see a reason why this happens, and it breaks the resulting configuration when things like MAC addresses or names are included in the remote port.

This is just a 1-line change to remove the port inheritance
