In my test environment, advance_expire_delta is frequently greater than
the fixed LAPIC_TIMER_ADVANCE_ADJUST_MAX. And this will hinder the
adjustment.

Supplementary details:

I have tried to backport timer related features to our production
kernel.

After completed, i found that advance_expire_delta is frequently greater
than the fixed value. It's necessary to trun the fixed to dynamically
values.
