[BUG] dask_cudf.read_json seems to be freezing when given a path with large number of files

**Describe the bug**

dask_cudf.read_json seems to be freezing when given a path with large number of files. Providing the list of files directly works

Below seems to be freezing
```python3
text_ddf = dask_cudf.read_json(f'{INPUT_PATH}/data/*',engine='cudf',lines=True)
```

Below works
```python3
files = list(map(lambda x: os.path.join(data_path, x), os.listdir(data_path)))

text_ddf = dask_cudf.read_json(files,engine='cudf',lines=True)
```
