x86/lapic: Load LAPIC state at post_load
Load the LAPIC state during post_load (rather than when the CPU
starts).
This allows an interrupt to be delivered from the ioapic to
the lapic prior to cpu loading, in particular the RTC that starts
ticking as soon as we load it's state.
Fixes a case where Windows hangs after migration due to RTC interrupts
disappearing.
