    Revert "v4l2allocator: Remove unused variable"

    This reverts commit ad4480d53408a4d97ab531174ef37f258f3253c0.

    This reverts commit ec6b8b84af719d828ddd91c724e715c0b4a556bc.

commit 3591a91067232a8daeae6c27f000d9579ca4b0c7
Author: Nicolas Dufresne <nicolas.dufresne at collabora.co.uk>
Date:   Mon Nov 24 10:33:29 2014 -0500

    Revert "v4l2object: allow to automatic selection of dmabuf"

    This reverts commit e6c2ad5571e5dedb212287efe238eb450032cd4f.

This need further debugging. While doing short investigation, I at least
spotted 1 thing wrong, we check if we can import DMABUF in order to default to
exporting DMABUF, that is wrong of course. The only way to check if we can
export DMABUF is to actually export DMABUF, limitation of V4L2 API.
