When for raid0 metadata is updated outside mdmon it can happen that
memory corruption occurs due to too amount of memory is allocated
for imsm device structure.
1. imsm: FIX: mdmon crash during 2 raid0 arrays expansion
this patch is almost the same to sent earlier except 2 changes:
a) compilation problem
b) size should affect anchor size also
(added calculation changes extends space_needed variable also
this variable is used for anchor allocation)
so it replaces previous one.
2. imsm: FIX: sizeof_imsm_dev() can return too small value
size returned by sizeof_imsm_dev() describes minimum size of device
This is correct when both device maps has the same length
When device expands or shrinks we should return size that allows
for storing larger device information to avoid memory corruption.
