v4l2object: Pool might be NULL in decide allocation

Browse source 
If special stride is needed and downstream don't support VideoMeta,
pool might be NULL in order to let the baseclass create a generic
pool­. This would lead to assertion with on Exynos with:

gst-launch-1.0 -v filesrc location=mov ! qtdemux ! h264parse ! \
                    v4l2video8dec ! fakesink
