[ Upstream commit e750a4b1224142bd8dd057b0d5adf8a5608b7e77 ]

For scenarios, when source change is followed by VIDIOC_STREAMOFF
on output plane, driver should discard any queued OUTPUT
buffers, which are not decoded or dequeued.
Flush with HFI_FLUSH_INPUT does not have any actual impact.
So, fix it, by invoking HFI_FLUSH_ALL, which will flush all
queued buffers.
