Pavel Begunkov c21a8027ad io_uring/net: fix iter retargeting for selected buf ... When using selected buffer feature, io_uring delays data iter setup until later. If io_setup_async_msg() is called before that it might see not correctly setup iterator. Pre-init nr_segs and judge from its state whether we repointing.
