Detail: fix segfault during IMSM raid creation

It can be reproduced with non IMSM hardware and IMSM_NO_PLATFORM
environmental variable set. The array state is inactive when creating
an IMSM container. And the structure info is NULL because load_super()
always fails since no intel HBA information could be obtained.
