Hoan Tran 5f009361d6 ACPI / CPPC: Prevent cpc_desc_ptr points to the invalid data ...

commit 2324d15447 upstream.

When CPPC fails to request a PCC channel, the CPC data is freed
and cpc_desc_ptr points to the invalid data.

Avoid this issue by moving the cpc_desc_ptr assignment after the PCC
channel request.
