rtc: set the alarm to the next expiring timer
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. Fixes: 2b2f5ff00f63 ("rtc: interface: ignore expired timers when enqueuing new timers") Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
