[PATCH 4/5] net: establish single code path for setting edev parameters

[Sascha Hauer <s.hauer@pengutronix.de>]

We have net_set_ip(), net_set_gateway() and net_set_netmask() to set the
IP parameters of a network device. Most code pathes go through these
functions with the exception of setting the parameters through
globalvars on the command line. Explicitly call the accessors for this
code path as well so that all IP parameter settings go through them.
This is done in preparation to integrate a real network stack later.
