[PATCH] ui/gtk-gl-area: Remove extra draw call in refresh

[dongwon.kim@intel.com]

From: Dongwon Kim <dongwon.kim@intel.com>

This partially reverts commit 77bf310084dad38b3a2badf01766c659056f1cf2
which causes some guest display corruption when gtk-gl-area
is used for GTK rendering (e.g. Wayland Compositor) possibly due to
simulataneous accesses on the guest frame buffer by host compositor
and the guest.
