imsm: FIX: Check array alignment before expansion
It can occur that OROM creates array not aligned properly.
Expansion cannot be run in such cases. It is detected in analyse_change().
It is too late. This causes that metadata is in migration state already,
when expansion cannot be started.
This problem has to be detected before metadata is updated,
in all arrays in reshaped container.
