[U-Boot] [PATCH 1/1] cmd/host: avoid segmentation fault for 'host info'

[Heinrich Schuchardt]

Without the patch a segmentation fault is caused by 'host info' if
CONFIG_BLK=y:

    make sandbox_defconfig
    make
    ./u-boot
    => host bind 0 ../sct-amd64.img
    => host info 0
    dev       blocks path
      0 Segmentation fault

Use the platform data to find the filename.

Fixes: 8f994c860d91 ("sandbox: blk: Switch to use platdata_auto_alloc_size
for the driver data")
