With the patch below applied, host_block_dev structure was switched
to be placed in platdata rather than priv. The command "host info"
must be aligned with this change. Otherwise, we will see "Segmentation
Fault."
Fixes: 8f994c860d
("sandbox: blk: Switch to use platdata_auto_alloc_size for the driver data")
