Fix video initialized check for console

[Pan7]

Its suppose to be for https://github.com/ioquake/ioq3/blob/master/code/client/cl_console.c#L447

Maybe you could explain in your commit summary why this is the wrong check to use, and what effects it may have had?

[Pan7]

You can't know the linewidth/video is not initialized by checking the variable "width" but by checking "con.linewidth". Don't know what it affects.

@Pan7: I think @llbraughler was asking you to amend the commit message (and re-push your branch) so that the commit is self-contained and justifies the change, without a later reader having to refer to this Github pull request to understand it (the PR might not even exist any more, if Github becomes less popular in a few years' time and ioquake3 moves elsewhere).

http://chris.beams.io/posts/git-commit/ has some great notes on what makes a good git commit message.
