This postcore_initcall() created pernet_operations
are registered from ./lib directory, and they have
to go right after audit_net_ops.
uevent_net_init() and uevent_net_exit() create and
destroy netlink socket, and these actions serialized
in netlink code.
Parallel execution with other pernet_operations
makes the socket disappear earlier from uevent_sock_list
on ->exit. As userspace can't be interested in broadcast
messages of dying net, and, as I see, no one in kernel
listen them, we may safely move uevent_net_ops to pernet_sys
list.
