libfdt: fdt_node_offset_by_phandle(): Fix comparison warning

Browse Source 
With -Wsign-compare, compilers warn about a mismatching signedness
in a comparison in fdt_node_offset_by_phandle().

Uses a better suited bitwise NOT operator to denote the special value of
-1, which automatically results in an unsigned type.
