[PATCH 2/3] powerpc/boot: Fix treeboot-currituck CPU node lookup check

[Thorsten Blum <thorsten.blum@linux.dev>]

fdt_node_offset_by_prop_value() returns a negative error code on
failure - fix the check accordingly.

Fixes: 228d55053397 ("powerpc/47x: Add support for the new IBM currituck platform")
