v4l2_stateful_decoder: Close leaked file descriptors
When map_buffers_and_convert_to_i420() accesses DMABUF data, there is a
leak of an open file descriptor. VIDIOC_EXPBUF opens file descriptors
for the exposed DMABUF, but process_opaque_frame() fails to close it
after running VIDIOC_QBUF.
For long files, this creates an error: "Too many open files". This isn't
seen with any current test clips.
Close the opened file descriptors in map_buffers_and_convert_to_i420()
and process_opaque_frame() after they are used.
BUG=b:210004784
TEST=emerge+deploy+v4l2_stateful_decoder --file long_file.ivf --md5 on
trogdor and hana.
