qdev-monitor: fix segmentation fault on qdev_device_help()
Normally, qmp_device_list_properties() may return NULL when a device haven't special properties excpet Object and DeviceState properties, such as virtio-balloon-device. We just need check local_err instead of prop_list. Example: Segmentation fault (core dumped) The backtrace as below: Program received signal SIGSEGV, Segmentation fault. 0x00005555559af1a8 in error_get_pretty (err=0x0) at util/error.c:152 152 return err->msg; (gdb) bt func=0x55555574a6ca <device_help_func>, opaque=0x0, abort_on_failure=0) at util/qemu-option.c:1072 Signed-off-by: Gonglei <arei.gonglei@huawei.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
