imsm: Do not block volume creation when container has disks with mixed sector size

Currently when created container keeps disks with mixed sector size (few
4K disks and some 512 disks) there is no possibility to create volume from
disks with one sector size.
Allow volume creation when given disks are related with mixed container.
