[PATCH] ALSA: usb-audio: Don't store returned value and check for errors

[Muhammad Usama Anjum <musamaanjum@gmail.com>]

The returned value by create_autodetect_quirk isn't being used other
than in the success check on next line. Remove the return value
assignement. Check for error values instead of success check.
