Fixed issue with long names causing unbounded recursion
This was caused by any commit containing entries large enough to
_always_ force a compaction. This would cause littlefs to think that it
would need to split infinitely because there was no base case.
The fix here is pretty simple: treat any commit with only a single entry
as unsplittable. This forces littlefs to first try overcompacting
(fitting more in a block than what has optimal runtime), and then
failing that return LFS_ERR_NOSPC for higher layers to handle.
