Subject: Determine network configuration in dracut's check() function
References: bsc#980328
Patch-mainline: v0.8.16
Git-commit: 5caf691e4c2ee4d8fcdc4ac9810bdfa97fb1f757

To allow using the variables set by kdump_ifname_config() from other
functions than the caller, they cannot not be set in cmdline(),
because this function is called by dracut in a sub-shell.

Instead, parse the network configuration during check() and use
global variables to pass the configuration to cmdline().
