Description of problem:

Currently dracut-module-setup.sh will always configure dracut to use dhcp to configure a network environment.

But when the network env is configured to be a static network in first kernel, that code is broken, it will still pass cmdline like 'ip=eth0:dhcp' to dracut cmdline.d/40ip.conf.
That means when the machine is in a env w/o a dhcp server, network can't be setup correctly, any remote dump should fail.

Version-Release number of selected component (if applicable):


How reproducible:
100%

Steps to Reproduce:
1.configure a static network env
2.restart kdump service
3.crash the system
  
Actual results:
dracut will use dhcp to setup network

Expected results:
dracut will use a static configuration
