d5b16c273e Check for hit after upgrading hash bucket lock 
Lookup is repeated after request is identified as miss and hash bucket
lock is upgraded (in order to map missing cachelines). At this point
cachelines status might change and the request might turn out to be
a hit after all. Adding check for this condition removes unnecessary
calls to remap logic.

51455330ad Fix removing cores from cleaning policy 
After detaching a core if user wanted to remove inactive cores the
cleaning policy data would not be initialized and would bug-out on next
core add.

This check was incorrect, as cleaning policy core metadata lifetime is
not bound to core volume being open or not.
