media: omap3isp: Don't set streaming state on random subdevs

[ Upstream commit 7ef57be07ac146e70535747797ef4aee0f06e9f9 ]

The streaming state should be set to the first upstream sub-device only,
not everywhere, for a sub-device driver itself knows how to best control
the streaming state of its own upstream sub-devices.
