rtc: add data_race() in rtc_dev_poll()
The unlocked read of rtc->irq_data in rtc_dev_poll() can race with
the write in rtc_handle_legacy_irq() and also, theoretically, with
the write in rtc_dev_read().
These races should be safe (see inline comment), thus annotate the
read with data_race() for KCSAN.
