I'm not sure there's a great deal of benefit to that change, because
use of hw_error() in new code is rarely correct (it does an abort()
so it should never be used for guest-triggered conditions, which is
about the only time that you might be interested in a guest register
dump rather than just asserting). Most of its existing uses are in
crufty old device models.
