net: lwip: dns: Fix print of resolved IP address

The lwIP dns command only prints out cached resolved IP addresses.

When a hostname is first resolved and ERR_INPROGRESS is returned the
dns command prints out 0.0.0.0 instead of the resolved IP address.

Fix this by printing out host_ipaddr instead of the temporary ipaddr
that only is valid when ERR_OK is returned.

Fixes: 1361d9f4f00a ("lwip: dns: do not print IP address when a variable is specified")
