crypto: remove hoisted function

[vkarpov15]

Heya,

Re: Automattic/mongoose#2281, crypto and strict mode don't play nicely together:

$ node -v
v0.12.0
$ node --use_strict
> var c = require('crypto');
crypto.js:604
    function next(er, ret) {
    ^^^^^^^^
SyntaxError: In strict mode code, functions can only be declared at top level or immediately within another function.

This'll fix that particular issue

Thanks for reporting this. This was recently fixed in #9237

Thanks for fixing, much appreciated. Will this get backported to 0.10?

@vkarpov15 As far as I know, this issue doesn't affect node v0.10.x. Did you encounter a similar problem with node v0.10.x?

[vkarpov15]

Nope, I just didn't check 0.10. No further issues, thanks for your help.
