[media] videobuf2-core: move plane verification out of __fill_v4l2/vb…
…_buffer The plane verification should be done before actually queuing or dequeuing buffers, so move it out of __fill_v4l2_buffer and __fill_vb_buffer and call it as a separate step. This also makes it possible to change the return type of __fill_v4l2/vb_buffer to void. The dqbuf case took some special care: before removing a buffer from the done_list you have to verify that the receiving v4l2_buffer has enough room for all the planes. The number of planes can differ between buffers due to the fact that buffers for other formats can be prepared using VIDIOC_PREPARE_BUF.
