ovl: verify whiteout index entries on mount
Whiteout index entries are used as an indication that an exported overlay file handle should be treated as stale (i.e. after unlink of the overlay inode). Check on mount that whiteout index entries have a name that looks like a valid file handle and cleanup invalid index entries. For whiteout index entries, do not check that they also have valid origin fh and nlink xattr, because those xattr do not exist for a whiteout index entry.
