   ## What changes were proposed in this pull request?
   Fix NPE in deleteClassificationV2 when tag missing from Cassandra  
   
   Fixes a NullPointerException in deleteClassificationV2() when attempting to delete a tag that exists in Elasticsearch but not in Cassandra EntityGraphMapper.java:4772-4777 .
   
   Root cause: ES cleanup happens for missing tags but it doesn't prevent subsequent code from attempting to convert a null Tag object to AtlasClassification, causing NPE at line 4787 EntityGraphMapper.java:4787 .
   
   Fix: Add early return after queuing ES deferred operation when currentTag is null. This allows the ES cleanup to execute successfully via executeESPostProcessing() while preventing NPE.
   
   Impact: Playbooks using "set-classification" action will now succeed gracefully when encountering tags that exist in ES but not in Cassandra, restoring data consistency instead of failing with HTTP 500.
   
   ## How was this patch tested?
