It is possible that certain config levels are not available, even if the max level includes the level. There can be missing levels in some platforms. So ignore the level when called for information dump for all levels and fail if specifically ask for the missing level. Here the changes is to continue reading information about other levels even if we fail to get information for the current level. But use the "processed" flag to indicate the failure. When the "processed" flag is not set, don't dump information about that level.
