cpufreq: powernow-k8: Fix possible memory leak in powernowk8_cpu_init()
The memory allocated for data->powernow_table inside
powernow_k8_cpu_init_acpi() or find_psb_table() is not freed in one of
the error paths in powernowk8_cpu_init(). Fix that by adding a kfree().
Fixes: 1ff6e97f1d99 ("[CPUFREQ] cpumask: avoid playing with cpus_allowed in powernow-k8.c")
