Attachment: WithoutValidation.png
> `validate` is a bit heavy to check negative scalar resource
> -----------------------------------------------------------

> Key: MESOS-5921

>
> When subtract resources finished, we need to call {{Resources::validate}} to
> check if the scalar resource is negative so as to remove this resource if it
> is negative. This is a bit heavy as the {{Resources::validate}} did many
> validation stuffs, such as checking type, validating role, checking resource
> name etc, all of them are not necessary.
> We should introduce a new helper function {{isNegative}} to check if the
> resource is a negative scalar resource.
