CXL LSA v2.1 utilizes the region labels stored in the LSA for interleave

This comment doesn't make sense to me. If it's a CXL label, we continue to 
execute. There's no skipping. Or are you trying to say if it's CXL label, then 
checking of cookie value is unnecessary? But the cookie value still is being 
used later on. Maybe a bit more comments on what's going on here would be 
helpful.

Yes Dave, For CXL label cookie value is not required. Its being used for
non CXL labels only. Sure, I will elaborate the comments in next patch-set.
