Fix bug #7122 - Reading a large browselist fails (server returns invalid values in subsequent SMBtrans replies)
There are two problems:
1). The server is off-by-one in the end of buffer space test.
2). The server returns 0 in the totaldata (smb_vwv1) and totalparams (smb_vwv0)
fields in the second and subsequent SMBtrans replies.
This patch fixes both.
Jeremy.
