Public bug reported:

SRU Justification

[Impact]

* Kernel crashes when realsense application exits.

[Fix]

* Cherry-pick 'Revert "uvcvideo: Prevent new URBs being processed at stream 
stop"' from
Xilinx's linux kernel repo `linux-xlnx`, the original "uvcvideo: Prevent new 
URBs being processed at stream stop"
has made the wrong assumption that it can always retrieve a `struct 
uvc_streaming`
via uvc_queue_to_stream().

[Test Plan]

* Checked realsense application exits successfully after applying the
revert patch.

[Where problems could occur]

* Low potential for regression. The original patch is not in mainline.
