These file systems don't know of unix style access rights. Owning user are group are set via mount options (see 'man 8 mount') and can't be changed by chown. This is a shortcoming of the file system, not of chown.
Additionally, if the file system claims that chown() succeeded when it in fact did nothing, then that would be a bug in the file system driver, to be fixed by the kernel folks (that is, it is not coreutils' job to detect whether the chown() syscall has a buggy return value for your file system).
