> GridCacheOffheapManager.recreateCacheDataStore() calls updatePartitionCounter() under partStoreLock which may try to acquire checkpointReadLock.
> recreateCacheDataStore() method can be called with checkpointReadLock (on GridDhtPartitionsExchangeFuture.updatePartitionFullMap) 
> or without checkpointReadLock (GridDhtPartitionEvictor thread calls evictPartitionAsync),
> So, checkpoint can cause a deadlock if it happens in between.
> Seems, we should acquire checkpointReadLock before partStoreLock.
