From: David Hildenbrand <david@redhat.com>

If we warn about the block size being smaller than the default, we skip
some alignment checks.

This can currently only fail on x86-64, when specifying a block size of
1 MiB, however, we detect the THP size of 2 MiB.

Fixes: 228957fea3a9 ("virtio-mem: Probe THP size to determine default block size")
