[PATCH] libfdt: fix fdt_check_node_offset_ w/ VALID_INPUT

[Frank Mehnert <frank.mehnert-2ptZNfhJYoRaodhZ+FW2PA@public.gmane.org>]

fdt_check_node_offset_() checks for a valid offset but also changes the
offset by calling fdt_next_tag(). Hence, do not skip this function if
ASSUME_VALID_INPUT is set.

Actually this works similar to fdt_check_prop_offset_().
