[PATCH] smbclient fails with posix large reads

[Andrew Bartlett]

smbclient3 in master fails when we attempt to use the posix extensions
to read 16MB chucks at a time.  Attached is a fix, which also applies to
(at least) 3.5.

to reproduce:

smbclient //server/tmp

posix
get large_file

I've CC'd Alex who found the issue.

The simple issue is that smb_buffer_oob fails because it is told the
incorrect packet size, not taking into account that the packet may be a
large read&X.  There are lot of calls to smb_len() in the code - I
suspect this may not be the only one wrong...

Given this was for an OOB check, I wanted to run it past the list to
double-check it. 

Thanks,

Andrew Bartlett
