Certain VRs might be configured to use only the first output channel and so the mode for the second will be 0. Handle this gracefully.
Fixes: b9fa0a3acfd8 ("hwmon: (pmbus/core) Add support for vid mode detection per page bases") Signed-off-by: Paul Fertser <fercerpav@gmail.com> ---
Notes: Changes for v2: - Use more imperative style
