USB: storage: include Prolific Technology USB drive in unusual_devs list

Add a quirk entry for the Leading Driver UD-11 usb flash drive.

As Alan Stern told me, the device doesn't deal correctly with the
locking media feature of the device, and this patch incorporates it.

Compiled, tested, working.
