verity: short-circuit dm_bht_populate

If a node is verified, so are all its parents. This is because we
verify top down. So we can break as soon as we see a verfied node.
Its parents are already verified and populated.

BUG=chromium-os:9752
TEST=Ran dm-verity.git unit tests. Ran platform_DMVerityCorruption on H/W.
