[PATCH 1/2] ia64: topology: Fix an error handling path in cache_add_dev()

[Christophe JAILLET]

If kobject_init_and_add()fails, kobject_put() needs to be called.
Add the missing call which is already there a few lines below in another
error handling path.

Fixes: f19180056ea0 ("[IA64] Export cpu cache info by sysfs")

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