IloPXEDeploy.validate() is redendant

[Naohiro Tamura]

IloPXEDeploy.validate() has just two lines of the following code.
The method parent of parent class, PXEDeploy.validate() has called
driver_utils.validate_boot_mode_capability(task.node).
So IloPXEDeploy.validate() is not necessary.

      class IloPXEDeploy(pxe.PXEDeploy):
        def validate(self, task):
          driver_utils.validate_boot_mode_capability(task.node)
          super(IloPXEDeploy, self).validate(task)

    Remove IloPXEDeploy.validate()

    Removed IloPXEDeploy.validate(), because the method of the parent
    class, PXEDeploy.validate(), has already implemented the code which it
    added.
