net: suppress RCU lockdep false positive in twsk_net()
Calls to twsk_net() are in some cases protected by reference counting
as an alternative to RCU protection. Cases covered by reference counts
include __inet_twsk_kill(), inet_twsk_free(), inet_twdr_do_twkill_work(),
inet_twdr_twcal_tick(), and tcp_timewait_state_process(). RCU is used
by inet_twsk_purge(). Locking is used by established_get_first()
and established_get_next(). Finally, __inet_twsk_hashdance() is an
initialization case.
It appears to be non-trivial to locate the appropriate locks and
reference counts from within twsk_net(), so used rcu_dereference_raw().
