[PATCH] sched: Remove redundant code from can_migrate_task()

There is no opportunity to return 1 if tsk_cache_hot is true and the expression (env->sd->nr_balance_failed > env->sd->cache_nice_tries) is false. Meanwhile, it's unnecessary to judge whether tsk_cache_hot is true or false after being filtered by previous judgment. Signe
