[encrypted-media] Remove note recommending setMediaKeys() be called before providing media data

ddorwin has just created a new issue for 
https://github.com/w3c/encrypted-media:

== Remove note recommending setMediaKeys() be called before providing 
media data ==
This is the remaining item from the discussion in  #8.

The spec currently contains the following non-normative note:

> As a best practice, applications should create a `MediaKeys` object 
and call `setMediaKeys()` before providing media data (for example, 
setting the `src` attribute). This avoids potential delays in some 
implementations.

@adrianba [suggested this order in bug 
19156](https://www.w3.org/Bugs/Public/show_bug.cgi?id=19156#c2), and 
the note was originally committed in 
3641e615bf4394890e4c3ddcd473963e71e249b7.

There may be a delay as the fix for #8 acknowledges, but it's not 
clear that the delay would be differ based on the order. In addition, 
the note discourages use of `encrypted` events to initiate the EME 
flow.

I recommend we remove the note.
