Regression: FTP client hangs after executing dir and get commands

Tested in vbox 3.2.2. Happens since rev. 42674:

http://svn.reactos.org/svn/reactos?view=rev&revision=42674

There is nothing interesting in debug log.
Warning. This bug is being blocked by CORE-4958

To reproduce:

• open cmd, type: "ftp ftp.opera.com" and press enter
• provide username (Anonymous) and password(just press enter);
• type dir or ls and press enter

Command will be executed and content will appear, but ftp client will not return to prompt and will eventually timeout(simplified example):

ftp> dir
227 Entering Passive Mode ()
150 Here comes the directory listing.
[ftp contents]

It should look like this instead:

ftp> dir
227 Entering Passive Mode ()
150 Here comes the directory listing.
[ftp contents]
226 Directory send OK.
