[PATCH nft,v3 7/9] mnl: restore --debug=netlink output with sets

[Pablo Neira Ayuso <pablo@netfilter.org>]

(null) (null) b size 1

The debugging output displays table and set names as (null). This patch
sets the table and name before displaying the netlink debugging, then
unset them to not break the extended error support.

Fixes: 086ec6f30c96 ("mnl: extended error support for create command")
