Subject: ALSA: usb-audio: Fix mixer ctl regression of Native Instrument devices

From: Takashi Iwai <tiwai@suse.de>

commit c4a359a0049f2e17b012b31e801e96566f6391e5 upstream.

The commit [da6d276957ea: ALSA: usb-audio: Add resume support for
Native Instruments controls] brought a regression where the Native
Instrument audio devices don't get the correct value at update due to
the missing shift at writing.  This patch addresses it.

Fixes: da6d276957ea ('ALSA: usb-audio: Add resume support for Native Instruments controls')
