[Bug 1299557] [NEW] cryptsetup luksFormat fails with -s <keysize>

[mpb]

Public bug reported:

I installed beta2 of 14.04 yesterday.  Today, I am trying to manually
create an encrypted partition.  If I specify a key size to cryptsetup
with -s, cryptsetup fails as follows.

root at slab:~# cryptsetup -y -s 128 luksFormat /dev/sda6
WARNING!
========
This will overwrite data on /dev/sda6 irrevocably.
Are you sure? (Type uppercase yes): YES
Enter passphrase:

device-mapper: remove ioctl on temporary-cryptsetup-2231 failed: No such device or address
device-mapper: remove ioctl on temporary-cryptsetup-2231 failed: No such device or address

After the above, luksDump shows all 8 key slots as DISABLED.

Without -s, cryptsetup will succeed, as follows.
