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
