Michael Grzeschik 43cd002387 usb: gadget: uvc_video: add worker to handle the frame pumping 
This patch changes the function uvc_video_pump to be a separate
scheduled worker. This way the completion handler of each usb request
and every direct caller of the pump has only to schedule the worker
instead of doing the request handling by itself.

Moving the request handling to one thread solves the locking problems
between the three queueing cases in the completion handler, v4l2_qbuf
and video_enable.

Many drivers handle the completion handlers directly in their interrupt
handlers. This patch also reduces the workload on each interrupt.
