Subject: [PATCH v1] kobject: Drop unneeded conditional in __kobject_del()

__kobject_del() is called from two places, in one where kobj is dereferenced
before and thus can't be NULL, and in the other the NULL check is done before
call. Drop unneeded conditional in __kobject_del().

It is possible after refactoring kobject_del(). Though I decided to do it in
a separate change (no need to backport) for better test coverage.
