9pnet_rdma: check token type before int conversion
When parsing options, make sure we have found a proper token before doing a numeric conversion. Without this check, the current code will end up following random pointers that just happened to be on the stack when this function was called, because match_token() will not touch the 'args' list unless a valid token is found.
