Fixes these userspace compilation errors when rdma_user_rxe.h is compiled
alone:

rdma/rdma_user_rxe.h:59:20: error: field ‘_sockaddr’ has incomplete type
   struct sockaddr  _sockaddr;
                    ^~~~~~~~~
rdma/rdma_user_rxe.h:60:22: error: field ‘_sockaddr_in’ has incomplete type
   struct sockaddr_in _sockaddr_in;
                      ^~~~~~~~~~~~
rdma/rdma_user_rxe.h:61:23: error: field ‘_sockaddr_in6’ has incomplete type
   struct sockaddr_in6 _sockaddr_in6;
                       ^~~~~~~~~~~~~
