Destroying a buffer view

When we don't need a buffer view any more, we should destroy it.

How to do it...

1. Take a logical device and store its handle in a variable of type VkDevice named logical_device.
2. Use the buffer's view handle and initialize a variable of type VkBufferView named buffer_view with it.
3. Call vkDestroyBufferView( logical_device, buffer_view, nullptr ). Provide the handle of the logical device, the handle of the buffer view, and a nullptr value.
4. For safety reasons, assign the VK_NULL_HANDLE value to the buffer_view variable.

How it works...

Buffer views are destroyed using the vkDestroyBufferView() function:

if( VK_NULL_HANDLE != buffer_view ) { 
  vkDestroyBufferView( logical_device, buffer_view, nullptr ); 
  buffer_view = VK_NULL_HANDLE; 
}

To avoid unnecessary function calls, we check whether the buffer view's handle is not empty before we call a buffer view destroying function.
