[PATCH] ssh client can't be compiled without interactive authentication

[peterpawn]

Compiling dropbear without ENABLE_CLI_INTERACT_AUTH results in an error ...
 a needed member of "clientsession" structure from session.h isn't included.
Because I can't see a direct coherence between "no interactive
authentication" and "unencrypted connection", my proposed change is to
declare "cipher_none_after_auth" in any case (a simple #endif has to move
one line up).
