topology: Fix up build warning in topology_is_visible()

Browse Source 
Commit aa63a74d45 ("topology/sysfs: Hide PPIN on systems that do not
support it.") caused a build warning on some configurations:

drivers/base/topology.c: In function 'topology_is_visible':
drivers/base/topology.c:158:24: warning: unused variable 'dev' [-Wunused-variable]
  158 |         struct device *dev = kobj_to_dev(kobj);

Fix this up by getting rid of the variable entirely.
