[PATCH 2/2] wireshark: Drop needless comment in dissect_xdr_bytes()

In the dissect_xdr_bytes() there's a comment that the string
allocated by xdr_bytes() can't be freed using xdr_free(). Well,
that is expected because xdr_bytes() used plain calloc() AND the
string is not an XDR struct but plain 'char *' type. Passing it
to xdr_free() must result in weird things happening.
