Subject[PATCH 2/12] Use find_task_by_vpid in autid 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.
