Michael Grzeschik db11d8c72a usb: gadget: uvc: giveback vb2 buffer on req complete ...

commit 9b969f93bcef9b3d9e92f1810e22bbd6c344a0e5 upstream.

On uvc_video_encode_isoc_sg the mapped vb2 buffer is returned
to early. Only after the last usb_request worked with the buffer
it is allowed to give it back to vb2. This patch fixes that.
