HID: wacom: fix kobject reference count leak

When sysfs_create_files() fails in wacom_initialize_remotes() the error
is returned and the cleanup action will not have been registered yet.

As a result the kobject???s refcount is never dropped, so the
kobject can never be freed leading to a reference leak.

Fix this by calling kobject_put() before returning.
