daemon/worker: decrease log level of uv_udp_connect() failure

In particular, ENETUNREACH happens on systems without IPv6,
and it doesn't make much sense to log about that by default:
  [io    ] Failed to establish udp connection: address not available

Introduced in 82e1d596 (v6.0.9).

Also log the IP address.
