Oleg Nesterov 6b6482bbf6 mempolicy: remove the "task" arg of vma_policy_mof() and simplify it 
1. vma_policy_mof(task) is simply not safe unless task == current,
   it can race with do_exit()->mpol_put(). Remove this arg and update
   its single caller.

2. vma can not be NULL, remove this check and simplify the code.
