net: Convert uevent_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 make uevent_net_ops async.
