We are spending way too much effort on qdio-internal bookkeeping for QAOB management & caching, and it's still not robust. Once qdio's TX path has detached the QAOB from a PENDING buffer, we lost all track of it until it shows up in a CQ notification again. So if the device is torn down before that notification arrives, we leak the QAOB. Just have the driver take care of it, and simply pass down a QAOB if they want a TX with async-completion capability. For a buffer in PENDING state that requires the QAOB for final completion, qeth can now also try to recycle the buffer's QAOB rather than unconditionally freeing it. This also eliminates the qdio_outbuf_state array, which was only needed to transfer the aob->user1 tag from the driver to the qdio layer.
