Markus Armbruster c525436e69 hw: Don't use hw_error() for machine initialization errors
Printing CPU registers is not helpful during machine initialization.
Moreover, these are straightforward configuration or "can get
resources" errors, so dumping core isn't appropriate either.  Replace
hw_error() by error_report(); exit(1).  Matches how we report these
errors in other machine initializations.
