content: fix example in "Go concurrency patterns" article

To quote Tim Scheuermann, who alerted me to this issue:

	The text states that the channel should be buffered for the last
	example to work, but the channel is already buffered. I tried to
	use the codereview tool to commit the patch, but it refuses to
	work on a github repository. The fix is trivial, remove the
	buffer from line 2 of the example.

Thanks to Ivan Kurnosov for finding it in the first place.
