Christopher Haster e5a6938faf Fixed possible infinite loop in deorphan step ...

Normally, the linked-list of directory pairs should terminate at a null
pointer. However, it is possible if the filesystem is corrupted, that
that this linked-list forms a cycle.

This should never happen with littlefs's power resilience, but if it does
we should recover appropriately.

Modified lfs_deorphan to notice if we have a cycle and return
LFS_ERR_CORRUPT in that situation.
