Use find_task_by_vpid in taskstats
The pid to lookup a task by is passed inside taskstats code via genetlink message. Since netlink packets are now processed in the context of the sending task, this is correct to lookup the task with find_task_by_vpid() here. Besides, I fix the call to fill_pid() from taskstats_exit(), since the tsk->pid is not required in fill_pid() in this case, and the pid field on task_struct is going to be deprecated as well.
