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.
