SSH: Fix state machine for ssh-agent authentication
In case an identity didn't match[0], the state machine would fail in state SSH_AUTH_AGENT instead of progressing to the next identity in ssh-agent. As a result, ssh-agent authentication only worked if the identity required happened to be the first added to ssh-agent. This was introduced as part of commit c4eb10e2f06fbd6cc904f1d78e4, which stated that the "else" statement was required to prevent getting stuck in state SSH_AUTH_AGENT. Given the state machine's logic and libssh2's interface I couldn't see how this could happen or reproduce it and I also couldn't find a more detailed description of the problem which would explain a test case to reproduce the problem this was supposed to fix. [0] libssh2_agent_userauth returning LIBSSH2_ERROR_AUTHENTICATION_FAILED Closes #2248
