netfilter: nf_log: replace BUG_ON by WARN_ON_ONCE when putting logger

Browse source

[ Upstream commit 259eb32971 ]

Module reference is bumped for each user, this should not ever happen.

But BUG_ON check should use rcu_access_pointer() instead.

If this ever happens, do WARN_ON_ONCE() instead of BUG_ON() and
consolidate pointer check under the rcu read side lock section.
