sysfs: Allow removal of symlinks in the sysfs root
Allow callers of sysfs_remove_link() to pass a NULL kobj, in which case sysfs_root will be used as the parent directory. This allows us to tear down top level symlinks created via sysfs_create_link(), which already has similar handling of a NULL parent object.
