vnc_refresh: return if vd->timer is NULL

Hi all,
calling vnc_update_client in vnc_refresh might have the unlikely side
effect of setting vd->timer = NULL, if the last vnc client disconnected.
In this case we have to return from vnc_refresh without updating the
timer, otherwise we cause a segfault.
