Simplify Dracut cmdline script
We don't actually need a real value for the root kernel param, and requiring one causes problems for things like the discovery ramdisk that don't pass in a disk= parameter. Dracut seems to be happy to take /dev/zero as the value, so we can just always use that. Change-Id: Ia724f0214c26aa18c6f8f41f2c48d7f25b52ee6c
