Calculate keyslots area size properly with detached headers.

When LUKS2 crypt_format() is called with detached header and custom data
alignment is requested, keyslots area is miscalculated. This mistake
is correctly detected by LUKS2 validation code but it's feature
regression with regard to LUKSv1 format.
