Rollup merge of #24167 - hauleth:remove-incorrect-example-from-mpsc, r=steveklabnik

Browse Source 
As beta is now released and is "suggested" version of `rustc` then there should be no code (in documentation) that will not compile with it. This one does not.

So according to [this great talk](http://delete-your-code.herokuapp.com/), I am doing what should be done.

//! });
//! rx.recv().unwrap();
//! ```
//!
//! Reading from a channel with a timeout requires to use a Timer together
//! with the channel. You can use the `select!` macro to select either and
//! handle the timeout case. This first example will break out of the loop
//! after 10 seconds no matter what:
//!
//! ```no_run
//! # #![feature(std_misc, old_io)]
//! use std::sync::mpsc::channel;
//! use std::old_io::timer::Timer;
//! use std::time::Duration;
//!
//! let (tx, rx) = channel::<i32>();
//! let mut timer = Timer::new().unwrap();
//! let timeout = timer.oneshot(Duration::seconds(10));
//!
//! loop {
//! select! {
//! val = rx.recv() => println!("Received {}", val.unwrap()),
//! _ = timeout.recv() => {
//! println!("timed out, total time was more than 10 seconds");
//! break;
//! }
//! }
//! }
//! ```
//!
//! This second example is more costly since it allocates a new timer every
//! time a message is received, but it allows you to timeout after the channel
//! has been inactive for 5 seconds:
//!
//! ```no_run
//! # #![feature(std_misc, old_io)]
//! use std::sync::mpsc::channel;
//! use std::old_io::timer::Timer;
//! use std::time::Duration;
//!
//! let (tx, rx) = channel::<i32>();
//! let mut timer = Timer::new().unwrap();
//!
//! loop {
//! let timeout = timer.oneshot(Duration::seconds(5));
//!
//! select! {
//! val = rx.recv() => println!("Received {}", val.unwrap()),
//! _ = timeout.recv() => {
//! println!("timed out, no message received in 5 seconds");
//! break;
//! }
//! }
//! }
//! ```
