Automatic merge from submit-queue

change predicate error format.

@davidopp @dchen1107 @mikedanese @yujuhong 

follow #20204.

address [FakePredicateError](https://github.com/kubernetes/kubernetes/pull/20204#discussion_r59237270) and [ErrFakePredicate](https://github.com/kubernetes/kubernetes/pull/20204#discussion_r59273190)

As for the rest suggestions ([NoDiskConflict](https://github.com/kubernetes/kubernetes/pull/20204#discussion_r59237340) and [NoVolumeZoneConflict](https://github.com/kubernetes/kubernetes/pull/20204#discussion_r59237419)), I would prefer to leave them as they now, for the reason given by @davidopp
