ctdb-vacuum: Fix the incorrect counting of remote errors
If a node fails to delete a record in TRY_DELETE_RECORDS control during
vacuuming, then it's possible that other nodes also may fail to delete a
record. So instead of deleting the record from RB tree on first failure,
keep track of the remote failures.
Update delete_list.remote_error and delete_list.left statistics only
once per record during the delete_record_traverse.
