This reduces the number of EAGAIN errors returned by TCP/IP in

when sending large SMBWriteX requests).
when sending large SMBWriteX requests). Fix case in which a portion of
data can in some cases not get written to the file on the server before the
file is closed. Fix DFS parsing to properly handle path consumed field,
