src: reset internal stateful objects

This patch allows you to atomically dump and reset stateful objects, eg.

 # nft list counters
 table ip filter {
        counter test {
              packets 1024 bytes 100000
        }
 }
 # nft reset quotas table filter
 counter test {
        packets 1024 bytes 100000
 }
 # nft reset quotas table filter
 counter test {
        packets 0 bytes 0
 }
