[patch 2/2] Use find_task_by_vpid in audit code



The pid to lookup a task by is passed inside audit code via netlink message.

Thanks to Denis Lunev, netlink packets are now (since 2.6.24) _always_
processed in the context of the sending task.  So this is correct to lookup
the task with find_task_by_vpid() here.
