For reviewers, Without this, non-mpath aware apps can't find their gw, therefore, we choose one here for netlink users. see line 658 below.

344–346

For reviewers, without these changes here + removal of nhop_select_func() from line 658 it was impossible to return RTA_MULTIPATH.
Since we overwrite nhgrp of rnd by nhop_select_func() to nhop. So this patch will restore the intended behavior.
