Granite speech - minor fixes to support training with the HF trainer (#38833)

* ensure the query is updated during training

avoid unused parameters that DDP does not like

* avoid a crash when `kwargs` contain `padding=True`

trainers often pass this argument automatically

* minor

* Remove mel_spec lazy init, and rename to mel_filters.
this ensures save_pretrained will not crash when saving the processor during training

* minor - most feature extractors has a `sampling_rate` property
