LU-6261 gnilnd: kgnilnd_check_rdma_cq race in error path.
It is possible for multiple threads to both be processing a
transaction error that causes the connection to close.
If the close path stalls after changing the conn state to CLOSING,
the tx_done path will put a tx in purgatory since the conn state is
not ESTABLISHED anymore. When the close path continues, it expects to
find that the conn->gnc_mdd_list is empty and assert if it isn't
empty.
Change the error code for the tx_done path so that we don't put this
tx in purgatory since we are closing the connection anyway.
