Revert of Remove pageview from map immediately (patchset #1 id:1 of https://codereview.chromium.org/2179283005/ )
Reason for revert:
Looks like this broke linux_asan embedder tests.
https://build.chromium.org/p/client.pdfium/builders/linux_asan/builds/1152/steps/embeddertests/logs/stdio
Original issue's description:
> Remove pageview from map immediately
>
> There seems to be an ownership issue in the page annotation code where removing
> the annotations can result in removing the parent page view. This is fine except
> that removing the parent page view removes the annotations and you can end up
> with a use-after-free.
>
> This CL removes the page view from the documents page map immediately and then
> proceeds with the cleanup. Then, if we try to remove that page again it won't
> be found and we won't double free.
