Remove DumpWithoutCrashing for bug 1090859

I added this DumpWithoutCrashing to investigate
https://crbug.com/1090859. This has never been hit, but I forget to
remove it. In the meantime, the number of crashes quickly vanished to
almost zero and nobody continued working on this bug.

Time to remove it! This reverts:
https://chromium-review.googlesource.com/c/chromium/src/+/2241672

Note: A new different bug appeared recently:
https://bugs.chromium.org/p/chromium/issues/detail?id=1262203
They are a priori not related, because they are failing on a different
CHECK on the same function.
