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.

The function `Query` takes a slice of database connections and a `query` string. It queries each of the databases in parallel and returns the first response it receives:
func Query(conns []Conn, query string) Result {

+ ch := make(chan Result)
for _, conn := range conns {
