Subject: ALSA: usb-audio: Fix bogus error return in snd_usb_create_stream()

From: Takashi Iwai <[email protected]>

commit 4763601a56f155ddf94ef35fc2c41504a2de15f5 upstream.

The function returns -EINVAL even if it builds the stream properly. The bogus error code sneaked in during the code refactoring, but it wasn't noticed until now since the returned error code itself is ignored in anyway. Kill it here, but there is no behavior change by this patch, obviously.
