uring: Fix the code broken when zero-copy send is enabled.



Without this fix, the program will hang in the target side.
If we use SPDK NVMe-of target with tcp transport with uring,

./scripts/rpc.py sock_impl_set_options --enable-zerocopy-send-server -i uring

Then we use nvmf initiator to test, the program hangs.
