fix: initialize known_hosts output entry

Browse Source 
ssh_session_get_known_hosts_entry() could return SSH_KNOWN_HOSTS_OK without initializing *pentry, leaving callers with an undefined output pointer.

Initialize *pentry to NULL at function entry so every return path leaves the output in a defined state.
