Revert of Use modifed URLRequest API in net/cert_net

Revert of Use modifed URLRequest API in net/cert_net (patchset #1 id:1 of https://codereview.chromium.org/2330873002/ )

Reason for revert:
This part of the big CL makes net unittests run on android bot to be flaky.

Original issue's description:
> Use modifed URLRequest API in net/cert_net
>
> This cl splits the big CL with changes to net/ folder and
> has changes only to net/cert_net according to the
> changes to URLRequest API.
>
> What the big cl does:
> It modifies net/ clients that use URLRequest API as long as
> URLRequest::Read returns int net errors and
> URLRequest::Delegate and NetworkDelegate methods
> (for example, OnResponseStarted or OnCompleted) have int
> net_error in the arguments now.
>
> The reason behind splitting the CL into small one is that
> an android bot started to be unstable and unittests became
> flaky. It was not possible to locate the problem and the
> decision was to split the CL and upload small parts with a
> 6+ hours interval in order to make it possible to locate
> the problematic code.

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
