Haiwei Li cdfd35ed3d hv: s3: enable lapic earlier ...

After Service VM OS resumes from s3, BSP starts APs asynchronously,
followed by IPIs to APs to resume tsc. This process takes place in
function `host_enter_s3`. While, APs' lapic are not ready to accept IPI
interrupt, so BSP fails to resume tsc.

So enable lapic earlier to make sure that APs are ready.
