[media] v4l: soc-camera: fix multiple simultaneous user case
A recent patch has introduced a regression, whereby a second open of an soc-camera video device breaks the running capture. This patch fixes this bug by guaranteeing, that video buffers get initialised only during the first open of the device node.
