[PATCH 5.4 324/453] media: ipu3-cio2: Remove traces of returned buffers

[Greg Kroah-Hartman]

From: Sakari Ailus <sakari.ai...@linux.intel.com>

commit 61e7f892b5ee1dd10ea8bff805f3c3fe6e535959 upstream.

If starting a video buffer queue fails, the buffers are returned to
videobuf2. Remove the reference to the buffer from the driver's queue as
well.
