Update state machine for ssh connection when system goes to off.

Currently when system goes to off state, we are not updating ssh
connection to disconnected state. Due to which if any tests are
having multiple IPL's then ssh API won't work once system comes
back.

This patch fixes this issue, by properly updating ssh connection
to SSHConnectionState.DISCONNECTED state when ever system
reaches standby state in state machine.
