On non-x86 builds, we now get a harmless warning:
drivers/hwtracing/intel_th/msu.c:783:21: error: unused variable 'i' [-Werror,-Wunused-variable]
int ret = -ENOMEM, i;
^
drivers/hwtracing/intel_th/msu.c:863:6: error: unused variable 'i' [-Werror,-Wunused-variable]
int i;
^
Add the matching #ifdef.
Fixes: ba39bd830605 ("intel_th: msu: Switch over to scatterlist")
