Subject: [PATCH -next] intel_th: msu: Remove set but not used variable 'last'

Fixes gcc '-Wunused-but-set-variable' 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]

It is never used since introduction in commit
