Subject: [PATCH 2/2] ia64: topology: Slightly simplify code

cpu_cache_sysfs_exit() already clears '&all_cpu_cache_info[cpu].kobj'. So
there is no need to do it twice.

Remove the redundant memset() and slightly simplify code.

This patch is provided as-is and is not even compile tested. I don't have the
cross-building toolchain for that.
