platform/x86: thinkpad_acpi: re-initialize ACPI buffer size when reuse
commit 720ef73d1a239e33c3ad8fac356b9b1348e68aaf 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.
