[IPV4]: Fix ip command line processing.
Recently the documentation in Documentation/nfsroot.txt was
update to note that in fact ip=off and ip=::::::off as the
latter is ignored and the default (on) is used.
This was certainly a step in the direction of reducing confusion.
But it seems to me that the code ought to be fixed up so that
ip=::::::off actually turns off ip autoconfiguration.
This patch also notes more specifically that ip=on (aka ip=::::::on)
is the default.
