An L2 KVM guest fails to boot inside a pSeries LPAR when booted with a

crashes when it is booted with a memory greater than 128 GB and a PCI
device is hotplugged later.
The issue arises from a conditional check for `levels > 1`
Full Unit Access (FUA) is an optimization where a disk write with the
flag set will be persisted to disk immediately instead of potentially
remaining in the disk's write cache.
