drivers/rtc/rtc-m41t93.c: don't let get_time() reset M41T93_FLAG_OF
If the rtc reports the time might be invalid due to oscillator failure, M41T93_FLAG_OF flag must not be reset by get_time() as the read operation doesn't make the time valid. Without this patch, only the first get_time() reported an invalid time, the second get_time() reported a valid time althought the reported time is probably wrong due to oscillator failure. Instead of resetting in get_time(), with this patch M41T93_FLAG_OF is reset in set_time() when a valid time is to be written.
