apparmor: remove the "task" arg from may_change_ptraced_domain()
Unless task == current ptrace_parent(task) is not safe even under rcu_read_lock() and most of the current users are not right. So may_change_ptraced_domain(task) looks wrong as well. However it is always called with task == current so the code is actually fine. Remove this argument to make this fact clear. Note: perhaps we should simply kill ptrace_parent(), it buys almost nothing. And it is obviously racy, perhaps this should be fixed.
