Commit aad14ad3cf3a ("intel_th: msu: Add current window tracking") added the following gcc warning:
drivers/hwtracing/intel_th/msu.c: In function msc_win_switch: drivers/hwtracing/intel_th/msu.c:1389:21: warning: variable last set but not used [-Wunused-but-set-variable]
Fix it by removing the variable.
