Anna-Maria Behnsen 2367e28e23 timers/migration: Spare write when nothing changed
The wakeup value is written unconditionally in tmigr_cpu_new_timer(). When
there was no new next timer expiry that needs to be propagated, then the
value that was read before is written. This is not required.

Move the write to the place where wakeup value is changed changed.
