[xfs-btree-bugfix] Fix bug in XFS B+tree inode
In XFS source code, bb_leftsib and bb_rightsib (declared in xfs_format.h) are both of type __be32, which is an unsigned int32 (and not 64).
While I was there, I added Inode.ToString() to help me differentiate beween inodes: In Linux, inodes are identified by a unique ID.
