module-setup: Add permanent option to detect static ip address or not 

Dracut will die in the situation that dracut detects to use dhcp to
setup ip address, but kdump passes the ip address to it.

In commit 7ea50dc7a3, we start to use
option permanent to get the ip address in kdump_static_ip. If the
network is setuped by static, we will get the ip address, otherwise
getting none.

In commit c994a80698 which it used to
support ipv6 protocol, I miss the option permanent.

This patch is not a fixing patch, just pulls back something to make
kdump work as original.
