Status: Close ssh connection after requesting for service status

Without this patch everytime when user execute `crc status` command
there is a non terminated ssh connection stays. Same with when podman
Desktop tray make API request and soon we have lot of sshd processes.

This PR make sure close the ssh connection after service status is received.
