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
