Subject: [PATCH] vkd3d: Initialize vk_extensions in vk_init_device_caps().

Without LTO, gcc doesn't know that hresult_from_vk_result() will always return a
failure HRESULT for a failure VkResult, and so thinks that we might exit from
vkd3d_check_device_extensions() with a success HRESULT but without initializing
vk_extensions.
