      ptlrpc: Use after free of 'conn' in rhashtable retry

      Use after free of 'conn' in the uncommon case of
      rhashtable_lookup_get_insert_fast failing with -EBUSY or -ENOMEM

      Move OBD_FREE_PTR(conn) below the retry and set conn2 to NULL
      on error, propagating to conn and returning to the caller.

      Fixes: 37b29a8f70 ("LU-8130 ptlrpc: convert conn_hash to rhashtable");
