Subject: [PATCH 12/17] imsm: create mdinfo list of disks in a container from supertype

If getinfo_super is called on a container supertype we only get information
on first disk. As a parameter it uses reference to preallocated
mdinfo structure. Amending getinfo_super to return full list of disks
would require ammending all previous calls and subsequently freeing memory
allocated for mdinfo list.
Function container_content that returns a mdinfo list is written
specifically for assembly, performing actions not needed to just fill
mdinfo. It also does not include spares so is unsuitable.
As an alternative a new function getinfo_super_disks is created
to obtain information about all disks states in array.
Existing function sysfs_free is used to free memory
allocated by getinfo_super_disks.

Yes, this is needed, but is an example of something that can hopefully 
go away after Neil's rework of the data structures returned from a load 
operation.  We shouldn't need a custom routine to retrieve this list. 
It should be available directly from the supertype.
