fa07d83565 Revert "virtio-devices, vmm: Optimised async virtio device activation" 
This reverts commit f160572f9d.

There has been increased flakiness around the live migration tests since
this was merged. Speculatively reverting to see if there is increased
stability.

f160572f9d virtio-devices, vmm: Optimised async virtio device activation 
In order to ensure that the virtio device thread is spawned from the vmm
thread we use an asynchronous activation mechanism for the virtio
devices. This change optimises that code so that we do not need to
iterate through all virtio devices on the platform in order to find the
one that requires activation. We solve this by creating a separate short
lived VirtioPciDeviceActivator that holds the required state for the
activation (e.g. the clones of the queues) this can then be stored onto
the device manager ready for asynchronous activation.

b1bd87df19 vmm: Simplify MsiInterruptManager generics 
By taking advantage of the fact that IrqRoutingEntry is exported by the
hypervisor crate (that is typedef'ed to the hypervisor specific version)
then the code for handling the MsiInterruptManager can be simplified.

This is particularly useful if in this future it is not a typedef but
rather a wrapper type.
