Oliver Hartkopp 13dc8e9cc5 isobusfs: srv: check name length against the received message length ...

The Change Current Directory and Volume Status requests used the path
and volume name length from the request without checking it against
the received message length. Short messages with a big name length made
the server process stale content of the receive buffer as path or
volume name.

Check the name length against the message length, use le16toh() for the
CCD name length and fix the debug output of the volume name.
