caif: checking the wrong variable
In the original code we check if (servl == NULL) twice. The first time
should print the message that cfmuxl_remove_uplayer() failed and set
"ret" correctly, but instead it just returns success. The second check
should be checking the value of "ret" instead of "servl".
