[PATCH 2/3] image-host: fix 'unknown error' error message

[al.kochet at gmail.com]

From: Alexander Kochetkov <al.kochet at gmail.com>

Fix error message like this:
Can't add verification data for node 'fdt-1' (<unknown error>)

We get unknown error because we decode error as fdt error
but actually it is system error.
