Change ev.ptr nullptr early-out to happen only when there is not a previous allocation for address 0. Custom memory pools (like custom allocators for Vulkan memory pools) can allocate at address 0, so the previous code would cause the Tracy server to alloc(0), free(0) (but early out), then on the next alloc(0) it would have a MemAllocTwiceFailure (because it skipped the free).
