[gtk-vnc] Simplify logic in host open code

[Daniel P. Berrange <dberrange src gnome org>]

    Simplify logic in host open code
    
    The second else clause checks for conn_error != NULL twice and since we
    don't use it to determine the return value we can clear it
    unconditionally.
    
    * src/vncconnection.c: Simplify logic in vnc_connection_open_host_internal
