With a properly chained CBFS, there are no such entries (except one at
the end, maybe), and large empty regions are simply skipped because
there's an empty file entry.

Since we're in firmware with few recovery options, we don't want the
computer to die with a black screen if all that happened may be some
minor corruption in a data structure, and so we do a best-effort
recovery by trying to find a new entry point into the chain. The
theory being that it can't get worse.
