This reverts commit 2c2a7552dd6465e8fde6bc9cccf8d66ed1c1eb72. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. The original commit log for this change was incorrect, no "error handling code" was added, things will blow up just as badly as before if any of these cases ever were true. As this BUG_ON() never fired, and most of these checks are "obviously" never going to be true, let's just revert to the original code for now until this gets unwound to be done correctly in the future.
