ALSA: usb-audio: Drop superfluous interface setup at parsing 

We reset each interface that is being parsed for each stream, but this
is superfluous and even can lead to spurious errors.  Since the
interface is set up properly at opening the endpoint for each actual
stream operation, let's drop the superfluous one.
