Mario Limonciello 83217f1bcb rtc: Adjust failure return code for cmos_set_alarm() 
commit 1311a8f0d4b23f58bbababa13623aa40b8ad4e0c upstream.

When mc146818_avoid_UIP() fails to return a valid value, this is because
UIP didn't clear in the timeout period. Adjust the return code in this
case to -ETIMEDOUT.
