Commit 6f189a08c1 ("ui/gtk-egl: Check EGLSurface before doing
scanout") introduced a regression when QEMU is running with a
virtio-gpu-gl-device on a host under X11. After the guest has
initialized the virtio-gpu-gl-device, the guest screen only
shows "Display output is not active.".

Commit 6f189a08c1 moved all function calls in
gd_egl_scanout_texture() to a code path which is only called
once after gd_egl_init() succeeds in gd_egl_scanout_texture().
Move all function calls in gd_egl_scanout_texture() back to
the regular code path so they get always called if one of the
gd_egl_init() calls was successful.
