Synchronize VCPU states before reset
This is required to support keeping VCPU states across a system reset. If we do not read the current state before the reset, cpu_synchronize_all_post_reset may write back incorrect state information. The first user of this will be MCE MSR synchronization which currently works around the missing cpu_synchronize_all_states.
