cpufreq: fix racing issue for cpu hotplug

To eliminate racing between dbs timer handler and cpufreq_del_cpu,
using kill_timer instead of stop_timer to make sure timer handler
execution finished before other stuff in cpufreq_del_cpu.

BTW, fix a lost point of cpufreq_statistic_lock taking sequence.
