qemu-option: parse_option_bool(): use error_set()
Note that set_option_parameter() callers still expect automatic error reporting with QError, so set_option_parameter() calls qerror_report_err() to keep the same semantics. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>
