crypto: remove bogus /= 2 for pbkdf iterations
When calculating iterations for pbkdf of the key slot data, we had a /= 2, which was copied from identical code in cryptsetup. It was always unclear & undocumented why cryptsetup had this division and it was recently removed there, too. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.
