Only schedule wakeups when alarm is set outside of user wakeup offset

Before this change, a repeat wakeup was scheduled for the same alarm when the user was started. This caused a lot of unnecessary kernel reschedules and user start calls.

After this change, such repeat wakeups are not scheduled.
