ALSA: usb-audio: Remove redundant assignment to len
Variable len is set to zero but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: sound/usb/mixer.c:2713:3: warning: Value stored to 'len' is never read [clang-analyzer-deadcode.DeadStores].
