[ofw] Problem in building opensm with the 6001 compiler

Also see this comment:

	/*
	   Provide MAD context such that the call back will know what to do.
	   We have to keep the entire request structure so we know the CB.
	   Since we can not rely on the client to keep it around until
	   the response - we duplicate it and will later dispose it (in CB).
	   To store on the MADW we cast it into what opensm has:
	   p_madw->context.ni_context.node_guid
	 */
	p_query_req_copy = malloc(sizeof(*p_query_req_copy));
	if (!p_query_req_copy) {
		OSM_LOG(p_log, OSM_LOG_ERROR, "ERR 5511: "
			"Unable to acquire memory for query copy\n");
		osm_mad_pool_put(p_bind->p_mad_pool, p_madw);
		status = IB_INSUFFICIENT_RESOURCES;
		goto Exit;
	}
	*p_query_req_copy = *p_query_req;
	p_madw->context.ni_context.node_guid =
	    (ib_net64_t) (long)p_query_req_copy;

The (long) cast should probably be (uintptr_t) when saving and restoring the pointer.
