initrd.scripts: start_network(): Don't try to configure network when "ip" argument contains comma or colon We are sharing "ip" kernel command-line argument with kernel's IP PNP feature. Because we don't support the same syntax/features it's safe to assume that user wants to use kernel's IP PNP feature when argument contains a comma or colon.
