securityfs: fix securityfs_create_dir comment
If there is an error creating a directory with securityfs_create_dir, the error is propagated via ERR_PTR but the function comment claims that NULL is returned. This is a similar commit to 88e6c94cda322ff2b32f72bb8d96f9675cdad8aa ("fix long-broken securityfs_create_file comment") that did not fix securityfs_create_dir comment at the same time.
