migration/colo.c: Use cpu_synchronize_all_states()
cpu_synchronize_all_pre_loadvm() marks all vcpus as dirty, so the registers are loaded from CPUState before we continue running the vm. However if we failover during checkpoint, CPUState is not initialized and the registers are loaded with garbage. This causes guest hangs and crashes. Fix this by using cpu_synchronize_all_states(), which initializes CPUState from the current cpu registers additionally to marking the vcpus as dirty.
