[Pipelines] Fix ASR model types check
# What does this PR do?

This changes `list` to `dict` in the ASR pipeline's `check_model_type()`. 
Previously, a list was passed to the checker, so the model name extraction was never preformed [here](https://github.com/huggingface/transformers/blob/8ddbfe975264a94f124684a138a2a5ca89a2bd0d/src/transformers/pipelines/base.py#L810) and an error was raised:
```
The model 'SEWDForCTC' is not supported for automatic-speech-recognition.
```

Was there any real failure or just a warning ?
If warning it's fine, if failure we need a tests (model type checking should not be a hard error anyway)<|||||>@Narsil just a warning in the logs, the model was loading fine
