Which is what we're searching for -- so it's _possible_, albeit
vanishingly unlikely, that btrfs_search_slot() will actually return
zero, having found precisely what we wanted?
And in that case, path->slots[0] being zero is fine. And we shouldn't be
subtracting one from it to find the slot we want?
