It is possible to call STREAMON without the minimum number of
buffers queued. In this case the vb2_queue state will be set to
streaming but the start_streaming vb2_op will not be called.
Later when enough buffers are queued, start_streaming will
be called but vb2_is_streaming will already return true.
Also removed the queue state check in stop_streaming since it's
not valid there either.
