simpler printing for "lostpassword" link

[ktdreyer]

There's no need to have two lines that print the same "lostpassword" link in in wp-login.php. Skip the "else" and just print it.

even better, with the negative mark in the right place

Removes duplicate from code.

16498.diff​ is actually incorrect since there are actually 3 conditions here, not two. See 16498.2.patch​, where I've made this code a little more clear.

The "Intentionally empty" section (as labeled in 16498.2.patch​) was introduced in [6612]. We can rewrite the condition so that there's no need for it.

16498.3.patch​ is the refreshed lostpassword.patch​, which I guess simplifies the logic in the most obvious way.
