platform/x86: thinkpad_acpi: re-initialize ACPI buffer size when reuse
commit 720ef73d 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.
