cpufreq / stats: fix race between stats allocation and first usage This patch forces complete struct cpufreq_stats allocation for all cpus before registering CPUFREQ_TRANSITION_NOTIFIER notifier, otherwise in some conditions cpufreq_stat_notifier_trans() can be called in the middle of stats allocation, in this case cpufreq_stats_table already exists, but stat->freq_table is NULL.
