Fix issue during property updates to avoid resource leak in Property list
1)After applying the updates and committing the transaction, extra resource/slots will be occupied in the Pmem property list because keys that are zero will occupy extra space. This results in wastage of Pmem resources.
Query results: But when you query the properties of a node, it always gives correct output/result. i.e. gdb->get_node_description(.....); always gives correct result because it discards the keys which are zero while returning the query-result, but internally the slots in the Pmem property list leaks.
- Removed unused variable from property_list::build_dirty_property_list()
