This series is improving the stability of the usb uvc gadget driver. On
the unconditional event of a crash or intentional stop while using the
uvc v4l2 userspace device and streaming to the host, the setup was
sometimes running into use after free cases. We fix that.

  usb: gadget: uvc: stop pump thread on video disable
  usb: gadget: uvc: cleanup request when not in correct state
  usb: gadget: uvc: rework pump worker to avoid while loop
