Description

initramfs: Set elevator=noop on the rpool's disks

ZFS already sets elevator=noop for wholedisk vdevs (for all pools), but
typical root-on-ZFS installations use partitions. This sets
elevator=noop on the disks in the root pool.

Ubuntu 16.04 and 16.10 had this. It was lost in 17.04 due to Debian
switching to this upstream initramfs script.
