fa8fcf5f4c vhost: Move to upstream crate 
The vhost crate from rust-vmm is ready, which is why we do the switch
from the Cloud Hypervisor fork to the upstream crate.

At the same time, we rename the crate from vhost_rs to vhost.

ffaab46934 misc: Use a more relaxed memory model when possible 
When a total ordering between multiple atomic variables is not required
then use Ordering::Acquire with atomic loads and Ordering::Release with
atomic stores.

This will improve performance as this does not require a memory fence
on x86_64 which Ordering::SeqCst will use.

Add a comment to the code in the vCPU handling code where it operates on
multiple atomics to explain why Ordering::SeqCst is required.
