render/vulkan: fix memory type detection 

From a comment by emersion:

> There is a logic error here: we pass 0xFFFFFFFF to vulkan_find_mem_type, which
> returns an index, and then we logical-and that with mem_reqs.memoryTypeBits.
> Instead we should pass mem_reqs.memoryTypeBits to vulkan_find_mem_type and use
> the result for the memoryTypeIndex field directly. Ideally checking for errors
> (-1 return value) in case no memory type is suitable.

Closes: #3470
