rtc: ds3232: fix read on /dev/rtc after RTC_AIE_ON
The rtctest (tools/testing/selftests/timers/rtctest.c) found that
reading ds3232 rtc device immediately return the value 0x20 (RTC_AF)
without waiting alarm interrupt.
This is because alarm_irq_enable() of ds3232 driver changes RTC_AF
flag in rtc->irq_data. So calling ioctl with RTC_AIE_ON generates
invalid value in rtc device.
The lower-level driver should not touch rtc->irq_data directly.
