====================
net: avoid slow rcu synchronizations in cleanup_net()

RTNL is a contended mutex, we prefer to expedite rcu synchronizations
in contexts we hold RTNL.

Similarly, cleanup_net() is a single threaded critical component and
should also use synchronize_rcu_expedited() even when not holding RTNL.

First patch removes a barrier with no clear purpose in ipv6_mc_down()
