[PATCH 4/4] ui/gtk-egl: guest fb texture needs to be regenerated when reinitializing egl

[Dongwon Kim]

If guest fb is backed by dmabuf (blob-resource), the texture bound to the
old context needs to be recreated in case the egl is re-initialized (e.g.
new window for vc is created in case of detaching/reattaching of the tab)
