Commit c5036d61e0bed3f4f51391a145638b426825e69c ("media: au0828: drop
vbi_buffer_filled() and re-use buffer_filled()") broke video and vbi streaming.
The vb2_buffer struct was copied instead of taking a pointer to it, but
vb2_buffer_done() needs the real object, not a copy, since it is hooking
the buffer into a different list.
