   Thanks @KevinWikant for the PR.
   
   We have seen this bug coming up few times in last few months. And the PR 
seems to fix the bug.
   
   Although I am thinking could there be a case where the block can show up in 
both liveReplicas and decommissioning, which could lead to any unnecessarily 
call to invalidateCorruptReplicas()
   
   Edge case coming to my mind is when the we are considering the block on 
decommissioning node as useable but the very next moment, the node is 
decommissioned.
