zil_lwb_set_zio_dependency() can not set write ZIO dependency on previous LWB's write ZIO if one is already in done handler and set state to LWB_STATE_WRITE_DONE. So theoretically done handler of next LWB's write ZIO may run before done handler of previous LWB write ZIO completes. In such case we can not defer flushes, since the flush issue process is not locked. This may fix some reported assertions of lwb_vdev_tree not being empty inside zil_free_lwb().
