Patrick Delaunay cba487c7fc fdtdec: correct test on return of fdt_node_offset_by_phandle ...

The result of fdt_node_offset_by_phandle is negative for error,
so this patch corrects the check of this result in
fdtdec_parse_phandle_with_args.

This patch allows to have the same behavior with or without OF_LIVE
for the function dev_read_phandle_with_args with cell_name = NULL and
with invalid phandle.
