mnl: consistency checks across several netlink dumps
Obtain the generation ID before dumping the object lists. Then, check for generation ID updates when dumping the several lists that this needs. In case of interference, nft has to remove the stale objects and retry from scratch. This is complementary to the NLM_F_DUMP_INTR flag which is local to one single netlink dump.
