Oleg Nesterov ac8148d957 bpf: bpf_iter_task_next: use next_task(kit->task) rather than next_task(kit->pos) 
This looks more clear and simplifies the code. While at it, remove the
unnecessary initialization of pos/task at the start of bpf_iter_task_new().

Note that we can even kill kit->task, we can just use pos->group_leader,
but I don't understand the BUILD_BUG_ON() checks in bpf_iter_task_new().
