bcachefs: Add hash seed, type to inode_to_text()
This helped with discovering some filesystem corruption fsck has having
trouble with: the str_hash type had gotten flipped on one snapshot's
version of an inode.
All versions of a given inode number have the same hash seed and hash
type, since lookups will be done with a single hash/seed and type and
see dirents/xattrs from multiple snapshots.
