oplcok_break more information (PR#12734)

Hi!  After more work on the oplock_break problem, I've found the following
in my tcpdump-smb logging.  It seems that when ost5 (pid=26339 in the logs
that follow) requests access to the oplocked file comm.inf from ost6
(pid=5872) the oplock_break failes (this is NOT isolated to any one or two
systems on our network, just using these two as an example, and the server
reports no dropped packets using ifconfig.)  I tcpdumped these two
computers during the transaction and have found that the server sends an
SMBlockingX command to ost6, and ost6 responds with a packet that isn't as
long as the "normal" SMB ones that I see in the hex dumps everywhere else.
Matter of fact the usual 5th line of HEX text, if I'm not mistaken, begins
with the command number, and it is missing here.  What follows are the
tcp-dumps for ost5 and ost6 followed by the very long samba-log for the
time periods in question.  I do have tcpdumps for 3 other instances if we
need them.  Anybody have ANY ideas?  I aplogize for the lengthy email, but
I wanted to make sure the the proper information is out there and didn't
want to miss anything!  I stripped out some of the hex dump information to 
make it fit under the 40k limit for samba at samba.org.  Hope I didn't delete
any pertinant information!

Thanks!
Bruce
