ubus: fix uninitialized variable warning

Explicitly zero-initialize `obi` in `_args_get()` to avoid the following
compiler warning:

    .../ubus.c: In function ‘_args_get’:
    .../ubus.c:100:31: error: ‘obj’ may be used uninitialized [-Werror=maybe-uninitialized]
      100 |                         arg = ucv_object_get(obj, name, NULL);
          |                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
