> We should calculate the size of “found” rather than “cell” because the offset value may cause the difference heap size between “cell” and “found”.

> removeFromCellSet(cell);
> long s = heapSizeChange(cell, true);
> this.size.addAndGet(-s);

> {code}
> The wrong heap size of store will block the HRegion#doClose because the HRegion#memstoreSize will always be bigger than zero even if we flush the store.
