Need to follow new method signature for hyper-v driver

[Feilong Wang]

Now in Grizzly the method signature of "destory" for compute driver is as below:

def destroy(self, instance, network_info, block_device_info=None,
            destroy_disks=True):

But the hyper-v driver is still using the follow:

def destroy(self, instance, network_info=None, cleanup=True,
            destroy_disks=True):

Which will cause the destroy failure.
