mlxsw: spectrum_router: Don't reflect LINKDOWN nexthops
The kernel resolves the nexthops for a given route using FIB_LOOKUP_IGNORE_LINKSTATE which means a notification can be sent for a route with one of its nexthops being LINKDOWN. In case IGNORE_ROUTES_WITH_LINKDOWN is set for the nexthop netdev, then we shouldn't reflect the nexthop to the device's table. Once the nexthop netdev's carrier goes up we'll be notified using NH_ADD and reflect it to the device.

gt;rnode | [0 ] | [s ] Because the parent of the deleted node is the first level below the root and has only one child in the left-most slot, the intermediate level is shrunk and the node containing the single shadow is put in its place: root->rnode | [s ] The shrinker again sees a single left-most slot in a first level node and thus decides to store the shadow in root->rnode directly and free the node - which is a leaf node on the shadow node LRU. root->rnode | s Without the update callback, the freed node remains on the shadow LRU, where it causes later shrinker runs to crash. Pass the node updater callback into __radix_tree_delete_node() in case the deletion causes the left-most branch in the tree to collapse too. Also add warnings when linked nodes are freed right away, rather than wait for the use-after-free when the list is scanned much later.
