imsm: allow drives in a container regardless of sector size

IMSM doesn't allow to create arrays including drives with different
sector sizes. The initial idea was not to permit to combine drives
with different sector size in the same container. The problem is it
only worked for array creation. On array assemble there are no
calls to metadata handlers to see if drive is suitable for a container
(e.g. as a spare) and it leads to wrong configuration.

Revert the change and allow adding drives with different sector size
to the container.
