When multiple "ip=" dhcp related commands are specified, dracut
will die. Two "ip=dhcp" is a simple example.
For kdump cases, when the kernel command line contains "ip=dhcp"
which is inherited by kdump environment, the network dumping also
hits this.
To fix it, we can treat multiple dhcp related commands just as one.
