This fixes the following compile problem:
````
/route.c: In function 'rtnl_flush':
/route.c:45:15: error: ignoring return value of 'write' declared with attribute
'warn_unused_result' [-Werror=unused-result]
45 | (void)write(fd, "-1", 2);
| ^~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
ninja: build stopped: subcommand failed.
