wined3d: Do not create larger staging buffers than necessary in adapter_vk_copy_bo_address().
This greatly increases performance in "Discovery Tour by Assassin's Creed:
Ancient Egypt".
The application frequently performs small (< 1 kiB) uploads to a large (128 MiB)
buffer. Without this patch, we will always create and destroy a new Vulkan
memory allocation, and the Vulkan driver will waste time zeroing the entire
allocation.
