Subject: [PATCH] usb: musc: Remove unused list 'buffers'

From: "Dr. David Alan Gilbert" <linux@...blig.org>

Remove the unused list head 'buffers' and the
'struct free_record' which is also unused below it.

To me it looks like this has always been unused, but I've
not dug into why.

Build test only.
