node: Do not close connection with node on NeoFS status responses

Previously, storage node closed connection with the remote node on any
status response from it for configured period of time (e.g. 30s). This
was fundamentally incorrect since status responses can only come from
"healthy" nodes.

From now status responses don't affect inter-node connections.

Closes #2767.
