      IB/ipath: fix null deref during rdma ops · 39770264

      The problem was that node A's sending thread, which handles sending RDMA
      read response data, would write the trigger word, the last packet would
      be sent, node B would send a new RDMA read request, node A's interrupt
      handler would initialize s_rdma_sge, then node A's sending thread would
      update s_rdma_sge.  This didn't happen very often naturally but was more
      frequent with 1 byte RDMA reads.  Rather than adding more locking or
      increasing the QP structure size and copying sge data, I modified the
      copy routine to update the pointers before writing the trigger word to
      avoid the update race.
