ALSA: hpi: Check transport errors during HPI6000 adapter initialization

Browse source

create_adapter_obj() retrieves adapter information by calling
hpi6000_message_response_sequence(). This function reports transport-level
errors through its return value and DSP-reported errors via hr0.error.

The current code only checks hr0.error, causing transport-level errors to
be ignored. As a result, adapter initialization may continue with an
invalid response.

Check the return value of hpi6000_message_response_sequence() before
examining hr0.error.
