    KAFKA-6218 : Optimize condition in if statement to reduce the number of 
comparisons

    
    Changed the condition in **if** statement 
    **(schema.name() == null || !(schema.name().equals(LOGICAL_NAME)))** which
    requires two comparisons in worst case with
    **(!LOGICAL_NAME.equals(schema.name()))**  which requires single comparison
    in all cases and _avoids null pointer exception.
