When ext4 encryption is enabled, the directory entries are encrypted
so we need to create fewer directory entries to guarantee that they
will all fit in a single block.

Also, the encryption metadata takes up extended attribute room so we
can only add a single xattr to guarantee that the xattrs will fit in
the inode.
