rtc: set the alarm to the next expiring timer
[ Upstream commit 74717b28cb32e1ad3c1042cafd76b264c8c0f68d ]
If there is any non expired timer in the queue, the RTC alarm is never set.
This is an issue when adding a timer that expires before the next non
expired timer.
Ensure the RTC alarm is set in that case.
