fsck.ubifs: rebuild_fs: Filter invalid files
This is the 4/12 step of rebuilding. Filter out invalid files and drop
them, for example:
1. File has no inode node or inode nlink is zero
2. Nonconsistent file type between inode node and dentry nodes
3. File has no dentry nodes(excepts '/')
4. Encrypted file has no xattr information
5. Non regular file has data nodes
6. Directory/xattr file has more than one dentries
7. Xattr file has no host inode, or the host inode is a xattr
...
Valid xattr file will be inserted into corresponding host file's subtree.
