realtek: eth: create phylink before device registration

As soon as devm_register_netdev returns, the network
interface is "live" and the kernel can call rteth_open().
If the interface is brought up immediately (e.g., by a
userspace script), rteth_open will attempt to call
phylink_start(ctrl->phylink), which will crash the
system because ctrl->phylink has not been assigned yet.

Reorder probing sequence.

While we are here sort the variables by length.
