8cce23acb9 witness.idl: fix length calculation for witness_IPaddrInfoList 
If r->num is 0, we should not dereference r->addr.

Using ndr_size_witness_IPaddrInfoList() also make this much simpler
and avoids the magic 12.

183da1f9fd witness.idl: Change array type in IDL for the print function 
It is important that the generated print function checks r->messages
before de-referencing r->messages[num] as r->num can be non-zero
while r->messages is NULL.

There is not witness server in Samba and print functions are only
used during debugging and ndrdump in any case.

The change in the IDL does not change the header and the IDL
function is already nopull,nopush so only the print function changes.

Found by Douglas Bagnall using Honggfuzz and a new fuzzer for
Samba's NDR layer.
