You're going to have problems with this, because ESXi relies on client-side name resolution, which is unlikely to work over an SSH tunnel.
To get around this and get you to connect, try adding an entry into your hosts file with a name of your choosing and settings its IP 127.0.0.1 and connecting to that instead.
