vfs_fruit: use correct case FRUIT_RSRC_STREAM in readdir_attr_rfork_size()
This is a genuine bug, but luckily this would only impact configs which nobody
uses:
fruit:metadata = netatalk
fruit:resource = stream
With the above configuration the switch in readdir_attr_rfork_size() would hit
the default case and so always report resource forks as 0 bytes in size.
All deployment that I've seen that use fruit:resource=stream also use
fruit:metadata=stream, so the switch takes FRUIT_META_STREAM case which runs the
correct code readdir_attr_rfork_size_stream().
