rtc: fix the error in the function of cmos_set_alarm
There is a bug in the function of cmos_set_alarm. RTC alarm time for October
can't be set correctly.
For October: 0x0A will be written into the RTC region (MONTH_ALARM) in current
kernel. But in fact 0x10 should be written. Wildcards are also not handled
correctly.
