media: ipu3-cio2 Check num_planes and sizes in queue_setup

If num_planes is different than zero num_planes and sizes must be
checked to support the format.

Fix the following v4l2-compliance error:

Buffer ioctls (Input 0):
    fail: v4l2-test-buffers.cpp(717): q.create_bufs(node, 1, &fmt) != EINVAL
  test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: FAIL
