…nterface"

This reverts commit 4af8319.

Reason for revert: Clusterfuzz issue: https://bugs.chromium.org/p/chromium/issues/detail?id=1217599

Original change's description:
> RenderProcessHost should have only one active CodeCacheHost interface
>
> RenderProcessHost should only have one active CodeCacheHost interface.
> When a RenderProcess dies we reset the CodeCacheHost interface so a new
> one can be requested. Earlier we had a DCHECK asserting that this is
> indeed the case. This CL turns the DCHECK to report a bad message.
