netfilter: nf_tables: Audit log dump reset after the fact

Browse source

[ Upstream commit e0b6648b04 ]

In theory, dumpreset may fail and invalidate the preceeding log message.
Fix this and use the occasion to prepare for object reset locking, which
benefits from a few unrelated changes:

* Add an early call to nfnetlink_unicast if not resetting which
  effectively skips the audit logging but also unindents it.
* Extract the table's name from the netlink attribute (which is verified
  via earlier table lookup) to not rely upon validity of the looked up
  table pointer.
* Do not use local variable family, it will vanish.
