[PATCH] sched: Use proper type for runqueue's idle_at_tick.

[Rakib Mullick <rakib.mullick@gmail.com>]

 Searching over scheduler code for uses of idle_at_tick, tells that its been used for making TRUE/FALSE decision. But, its been declared as 'unsigned char', using 'bool' is more rational here. So, for consistency use 'bool' as idle_at_tick type instead of 'unsigned char'.
