fixup! snapshot: handle the scratch region correctly

Make virt_to_phys use the aligned and un-canonicalised version of its
argument for traversal.

This does not actually matter, because only certain bits are actually
taken from vmin by the (chained) `modify_ptes` iterator(s). However,
since it doesn't matter, this is probably better for clarity.
