4.4-stable review patch.  If anyone has any objections, please let me know.

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')
