Remove disk_cache::BackendImpl::OpenPrevEntry() and all users.

While working on https://codereview.chromium.org/542733002/ to fix
issue 410276, a question came up about how important OpenPrevEntry was
to maintain; it made that CL more complex and for what users?

It turns out, it's not really used. See
https://groups.google.com/a/chromium.org/forum/#!topic/net-dev/wlMR_zNJ85k
for a discussion.

Let's remove it and save ourselves some headaches.
