ASoC: compress: Clarify the intent of current compressed ops handling
For callbacks configuring the state of the components (trigger, set_params, ack and set_metadata) simplify the code a little and make intention clearer by aborting as soon as an error is encountered. The operation has already failed and there is nothing to be gained from processing the callbacks on additional components. The operations currently abort after the callbacks, so this simply shortens the error path. For callbacks returning information from the driver (copy, get_metadata, pointer, get_codec_caps, get_caps and get_params) only look for the first callback provided, currently the code will call every callback only returning the information provided by the last. Since we can only return one set of data, it makes no sense to request the data from every component. Again this just makes the currently supported feature set a little more clear.
