    Remove "ip=" overwrite to 40ip.conf
    
    Currently we overwrite 40ip.conf to make ip and ifname both at the first
    line. But getarg() of dracut doesn't have the limitation that all
    cmdline args should be at the first line. Therefore, we can remove the
    overwrite safely.
    
    After applying this patch, in 2nd kernel,
    
    kdump:/# cat /etc/cmdline.d/40ip.conf
     ip=eth0:dhcp
     ifname=eth0:52:54:00:b2:98:05
    kdump:/# source /usr/lib/dracut/dracut-lib.sh
    kdump:/# getarg ip
    ip=eth0:dhcp
    kdump:/# getarg ifname
    ifname=eth0:52:54:00:b2:98:05
