s3:libsmb: fix smb signing for fragmented trans/trans2/nttrans requests
Before we send the secondary requests we need to remove the old mid=>seqnum mapping and reset cli->mid and make the new mid=>seqnum mapping "persistent". The bug we had in cli_send_trans was this: The first cli_send_smb() incremented cli->mid and the secondary requests used the incremented mid, but as cli->outbuf still had the correct mid, we send the correct mid to the server. The real problem was that the cli_send_smb() function stored the seqnum under the wrong mid. cli_send_nttrans() was totally broken and now follows the same logic as cli_send_trans(). The good thing is that in practice the problem is unlikely to happen, because max_xmit is large enough to avoid secondary requests. metze
