NullPointerException in TcpDiscoverySpi with unresolved addresses

Ignite 2.17.0; Java 21.

`org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi#getEffectiveNodeAddresses` doesn't check for `null` values where it should.

https://github.com/apache/ignite/blob/ignite-2.17/modules/core/src/main/java/org/apache/ignite/spi/discovery/tcp/TcpDiscoverySpi.java#L1301

```java
/**
* Gets the {@code InetAddress}.
*
* @return the InetAddress or {@code null} if it is unresolved.
*/
public final InetAddress getAddress() {
return holder.getAddress();
}
```

This can lead to NPE during grid startup. We encounter this exception after updating Ignite from 2.16.0 to 2.17.0.

```

Start in modules/core/src/main/java/org/apache/ignite/spi/discovery/tcp/TcpDiscoverySpi.java at getEffectiveNodeAddresses and inspect how unresolved InetAddress values are handled by getAddress(). Reproduce the grid-startup path if possible and confirm that unresolved addresses no longer cause a NullPointerException.
