drivers/rtc/interface.c: fix alarm rollover when day or month is out-of-range
Commit f44f7f96a20a ("RTC: Initialize kernel state from RTC") introduced a
potential infinite loop. If an alarm time contains a wildcard month and
an invalid day (> 31), or a wildcard year and an invalid month (>= 12),
the loop searching for the next matching date will never terminate. Treat
the invalid values as wildcards.
