ALSA: scarlett2: Add missing error check to scarlett2_config_save()
[ Upstream commit 5f6ff6931a1c0065a55448108940371e1ac8075f ]
scarlett2_config_save() was ignoring the return value from
scarlett2_usb(). As this function is not called from user-space we
can't return the error, so call usb_audio_err() instead.
