qemu-img: fix error reporting for -object

Error reporting for user_creatable_add_opts_foreach was changed so that
it no longer called 'error_report_err' in:

  commit 7e1e0c1112

    qom: Clean up error reporting in user_creatable_add_opts_foreach()

Some callers were updated to pass in "&error_fatal" but all the ones in
qemu-img were left passing NULL. As a result all errors went to
/dev/null instead of being reported to the user.
