[PATCH nf 2/2] netfilter: nf_tables: set on dead bit when performing early element removal

[Pablo Neira Ayuso]

.commit call for sets is skipped if set->dead flag is set on, but this
flag is set on later in the commit path.

This also reintroduces the bug fixed in commit 7315dc1e122c8
("netfilter: nf_tables: skip set commit for deleted/destroyed sets").

Fixes: 1e3b9e1c77fe ("netfilter: nf_tables: call set ops .commit when building new ruleset blob")
