xen/time: Use the pv_ops steal_time.

In the past we were using do_stolen_account() to update the
stolen time and this was done when by calling account_steal_ticks().

The do_stolen_account() was called from xen_timer_interrupt(). The
xen_timer_interrupt() would be called periodically (or frequently)
depending on what the timer decided. We would piggy-back on the
timer IRQ to update the steal time and idle time (fixed by
'remove blocked time accounting from xen "clockchip"' patch).

Instead of piggy-backing on the timer interrupt lets do it
via the provided API pv-ops time calls - the steal_clock.
