[PATCH 03/11] ALSA: scarlett2: Add missing error check to scarlett2_usb_set_config()

["Geoffrey D. Bennett" <g@xxxxx>]

scarlett2_usb_set_config() calls scarlett2_usb_get() but was not
checking the result. Return the error if it fails rather than
continuing with an invalid value.

Signed-off-by: Geoffrey D. Bennett <g@xxxxx>
Fixes: 9e15fae6c51a ("ALSA: usb-audio: scarlett2: Allow bit-level access to config")
