The length of dentry name is calculated after the raw name is encrypted,
except for ubifs_link(), which could make the size of dir underflow.
Here is a reproducer:
touch $TMP/file
mkdir $TMP/dir
stat $TMP/dir
for i in $(seq 1 8)
do
ln $TMP/file $TMP/dir/$i
unlink $TMP/dir/$i
done
stat $TMP/dir
The size of dir will be underflow(-96).
Fix it by calculating dentry name's length after the name is encrypted.
