Commit d9e474ea56 overlooked the case where the target psize is even larger
than the host psize. One example is Alpha has 8K page size and migration
will start to crash the source QEMU when running Alpha migration on x86.
Fix it by detecting that case and set host start/end just to cover the
single page to be migrated.
FWIW, commit in question, which is d9e474ea56, has been applied after the
last released version to date, which is 7.2.0. So I guess this change is
not applicable to -stable.
