Cryptsetup keeps some sectors (between the physical LUKS header
and keyslot data) on disk untouched, unfortunatelly ext2/3/4 signature can
be there and blkid detects filesystem here instead of LUKS.
This patch wipes the first eight sectors on disk with zero during luksFormat.
This should be probably solved by physical header padding in next version.
