Chirantan Ekbote b9966c96c1 devices: Remove lifetime parameter from DescriptorChain ... The lifetime parameter on the DescriptorChain struct ensures that it doesn't outlive the GuestMemory that it references. However, this has the unfortunate effect that DescriptorChains cannot be sent across thread boundaries (because they don't have a static lifetime). Instead, have the DescriptorChain clone the GuestMemory instead. This ensures that the DescriptorChain will not outlive the GuestMemory while also allowing it to be sent across thread boundaries. dgreid - re-base and modify `next_async` to remove lifetime as well.
