cpufreq_stats: Disable cpu hotplug during stats table creation
During boot there is a possibility for two execution context to create
stats percpu variable concurrently. One called from cpufreq_stats_init
context and other as a part of policy notifier call back. This will
result in corrupted stats variable.
Disable cpu hotplug to avoid corruption.
