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