Andrew Jones 53f985584e KVM: arm64: pvtime: Fix stolen time accounting across migration ...

When updating the stolen time we should always read the current
stolen time from the user provided memory, not from a kernel
cache. If we use a cache then we'll end up resetting stolen time
to zero on the first update after migration.
