intel_th: msu: Remove set but not used variable 'last'
commit 9800db282dff675dd700d5985d90b605c34b5ccd upstream.
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.
