sound: usb: Return error if any member API fails

Currently, the driver undoes the previously done work on an
API failure, but it still returns 0(SUCCESS) as
internal_status in the QMI response. Hence AFE still queues
data leading to null pointer dereference.
Fix this by returning error on failure of any member routine.
