[SCSI] libosd: Fix NULL dereference BUG when target is not OSD conformant

Very old OSC's Target had a BUG in the Get/Set attributes where
it was looking in the wrong places for attribute lists length.
If used with the open-osd initiator, the initiator would dereference
a NULL pointer when retrieving system_information attributes.

Checks are added that retrieval of each attribute is successful
before accessing its value.
