mshv: Fix VpRootDispatchThreadBlocked value

This value in the VP stats page is used to track if the VP can be
dispatched for execution when there are no fast interrupts injected.

The original value of 201 was used in a version of the hypervisor
which did not ship. It was subsequently changed to 202 so that is the
correct value.
