Fam Zheng 10f5a72f70 virtio-blk: Fix double completion for werror=stop ... When a request R is absorbed by request M, it is appended to the "mr_next" queue led by M, and is completed together with the completion of M, in virtio_blk_rw_complete. During DMA restart in virtio_blk_dma_restart_bh, requests in s->rq are parsed and submitted again, possibly with a stale req->mr_next. It could be a problem if the request merging in virtio_blk_handle_request hasn't refreshed every mr_next pointer, in which case, virtio_blk_rw_complete could walk through unexpected requests following the stale pointers. Fix this by unsetting the pointer in virtio_blk_rw_complete. It is safe because this req is either completed and freed right away, or it will be restarted and parsed from scratch out of the vq later.
