exynos4210/mct: Avoid infinite loop on non incremental timers
Check for a 0 "distance" value to avoid infinite loop when the expired FCR timer was not programed with auto-increment. With this change the behavior is coherent with the same type of code in the exynos4210_gfrc_restart() function in the same file. Linux seems to mostly use this timer with auto-increment which explain why it is not a problem most of the time. However other OS might have a problem with this if they don't use the auto-increment feature.
