Ensure the driver gets always at least its minimum required number of buffers allocated by checking actual number of allocated buffers in vb2_reqbufs(). And free any partially allocated buffer queue with signaling an error to user space. Without this patch applications may wait forever to dequeue a filled buffer, because the hardware didn't even start after VIDIOC_STREAMON, VIDIOC_QBUF calls, due to insufficient number of empty buffers.
