fdt: check for fdt errors in fdt_create_phandle
fdt_create_phandle() was ignoring errors from fdt_set_phandle(). If an
error occurs, print an error message and return 0, which is an invalid
phandle. We also need to change the return type for fdt_create_phandle()
to indicate that it cannot return an error code.
