Fix: Handle exception during sol activate cmd

When there is any exception during StartConsole, the console must be
freed,without which it was wrongly assumeed that console is active.

Tested :
1.Disable SSH using systemctl stop obmc-console@xxx.service and
systemctl stop obmc-console@xxx.socket.
2.Activate sol multiple times. It should always give unspecified error
as response
