[PATCH 6.18 266/396] cpufreq: powernow-k8: Fix possible memory leak in powernowk8_cpu_init()

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Abdun Nihaal <[email protected]>

commit d5f8e5f6040d052d44fcbf4f31dd35145c0c8d7d upstream.

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().
