[RFC] lapic calibration results fix

[Cyrill Gorcunov <gorcunov@gmail.com>]

Ingo, Maciej,

it seems I found a bit strange code snippet in apic_32.c:setup_boot_APIC_clock.
We set local_apic_timer_verify_ok = 1 before checking the results. I think
the following patch make sense. Please take a look on.

---
We set lapic flag that clocksource calibration is
fine too early. Fix it.
