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.
