Type confusion error when running under UBSan

[ceeac]

This occurs with, and is brobably related to commit 47d9b80.

Steps to reproduce:

• Compile and link samples with gcc-15 with -fsanitize=undefined
• Start any sample that is derived from vkb::VulkanSampleC, e.g. SwapchainRecreation

Result:

$ ./vulkan_samples sample swapchain_recreation
