media: i2c: ov5695: Drop check for reentrant .s_stream()

The subdev .s_stream() operation shall not be called to start streaming
on an already started subdev, or stop streaming on a stopped subdev.
Remove the check that guards against that condition.

The streaming field of the driver's private structure is now unused,
drop it as well.
