Force evicting subframe in NavigationRequest::OnStartChecksComplete()

In the case when a main frame and its subframe both starts navigations
around the same time, if the main frame commits the navigation earlier
than its subframe, the subframe may be incorrectly put into BFCache
along with the main frame before reaching this method, causing errors
like [1] after https://crrev.com/c/5308025 is submitted.

This CL forces evicting subframe in such case.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
