ui: remove bogus call to graphic_hw_update() in vnc_listen_io

Just before accepting a new client connection the vnc_listen_io
method calls graphic_hw_update(). This is bogus because there
is a call to this method already in vnc_state_init() and the
client doesn't need up2date graphics console before reaching
that.
