Simon Tatham af6a19e962 sshproxy.c: add missing NULL check. ...

If you try to use a saved session for SSH proxying which specifies a
protocol that is not SSH or bare-SSH-connection, you get a clean error
return from the proxy setup code - *provided* it's at least a protocol
known to this particular build of PuTTY. If it's one so outlandish
that backend_vt_from_proto returns NULL, there'd have been a crash.

I don't think any such protocol currently exists, but if in the next
version of PuTTY some additional protocol becomes supported, it will
trip this error in the current version.
