USB: usb-skeleton.c: fix blocked forever in skel_read
In skel_read,the reader blocked in wait_for_completion before submit
bulk in urb.
Using processed_urb is for retaining the completion in the case that
previous interruptible wait in skel_read was interrupted and complete
before next skel_read. Replacing completion with waitqueue can avoid
working around the counting nature of completions
and fix the bug.
