Ceph can in some cases issue an async DIO request, in which case we can end up calling ceph_end_io_direct before the I/O is actually complete. That may allow buffered operations to proceed while DIO requests are still in flight. Fix this by incrementing the i_dio_count when issuing an async DIO request, and decrement it when tearing down the aio_req.
