rgw: cleanup for RGWDeleteObj::verify_permission()

- if the 'Effect' field of user policy and bucket policy
  is set to 'Allow', RGWDeleteObj::verify_permission()
  should return 0 instead of true;

- as the same with bucket policy, if the 'Effect' field
  of user policy is set to 'Deny', RGWDeleteObj::verify_permission()
  should return -EACCES instead of false;
