Subject[PATCH v2 20/31] net: Convert subsys_initcall() registered pernet_operations from net/sched
From
Date
psched_net_ops only creates and destroyes /proc entry,
and safe to be executed in parallel with any foreigh
pernet_operations.

tcf_action_net_ops initializes and destructs tcf_action_net::egdev_ht,
which is not touched by foreign pernet_operations.

So, make them async.
