[PATCH 12/12] Detail.c: call load_container for container subarrays

[mwilck@arcor.de]

Without calling load_container at this point, the
info structure may be missing some important information.
In particular, information about secondary DDF RAID levels
may be wrong if information is only read from a single disk.

If this fails, fall back to the previous code.
