ROOT_ITEMs in btrfs are referenced without knowing their actual "offset" value. To perform these searches using only two items from the key, the btrfs driver uses a special "btrfs_search_tree_key_type" function.
The algorithm used by that function to transform a 3-tuple search into a 2-tuple search was subtly broken, leading to items not being found if they were the first in their tree node.
This commit fixes btrfs_search_tree_key_type to properly behave in these situations.

Applied to u-boot/master, thanks!
Please disregard this patch as was mentioned in a followup email on the thread.
https://patchwork.ozlabs.org/patch/1085991/ implements a better way of addressing the problem and fixes a 2nd btrfs bug that was missed in this first revision.
Sorry for the mixup, Best,
