Vladimir Zapolskiy f501ed524b rtc: s3c: balance state changes of wakeup flag 
This change resolves a problem about unbalanced calls of
enable_irq_wakeup() and disable_irq_wakeup() for alarm interrupt.

Bug reproduction:

root@eb600:~# echo 0 > /sys/class/rtc/rtc0/wakealarm

WARNING: at kernel/irq/manage.c:361 set_irq_wake+0x7c/0xe4()
 Unbalanced IRQ 46 wake disable
