nft: Fix for add and delete of same rule in single batch

Another corner-case found when extending restore ordering test: If a
delete command in a dump referenced a rule added earlier within the same
dump, kernel would reject the resulting NFT_MSG_DELRULE command.

Catch this by assigning the rule to delete a RULE_ID value if it doesn't
have a handle yet. Since __nft_rule_del() does not duplicate the
nftnl_rule object when creating the NFT_COMPAT_RULE_DELETE command, this
RULE_ID value is added to both NEWRULE and DELRULE commands - exactly
what is needed to establish the reference.
