[NETNS]: Fix get_net_ns_by_pid
The pid namespace patches changed the semantics of find_task_by_pid without breaking the compile resulting in get_net_ns_by_pid doing the wrong thing. So switch to using the intended find_task_by_vpid. Combined with Denis' earlier patch to make netlink traffic fully synchronous the inadvertent race I introduced with accessing current is actually removed. Signed-off-by: Eric W.
