Aaron Ma 09e0fa8c02 platform/x86: thinkpad_acpi: re-initialize ACPI buffer size when reuse ...

commit 720ef73d1a upstream.

Evaluating ACPI _BCL could fail, then ACPI buffer size will be set to 0.
When reuse this ACPI buffer, AE_BUFFER_OVERFLOW will be triggered.

Re-initialize buffer size will make ACPI evaluate successfully.
