[PATCH] platform/x86: thinkpad_acpi: Fix uninitialized symbol

[Matthias Fetzer]

When the TPACPI_FAN_WR_ACPI_FANW branch is taken s stays uninitialized
and would be later used in a debug print.

Since the registers are always set to the same two static values inside the
branch s is initialized to 0.
