virtio-gpu-gl-pci console tries to make GL context before widget is realized leading to crash
Description of problem:
When `-vga none` is added to the command line, there is no crash.

When it is not, two `GtkGLArea` widgets are created: one for VGA and one for `virtio-gpu-gl-pci`. Only the first one is realized, but the virgl code tries to create a GL context for the second. In `gd_gl_area_create_context`, `gtk_widget_get_window(vc->gfx.drawing_area)` evaluates to NULL a crash follows:

Steps to reproduce:
1. Get OVMF. On Arch Linux, you can install the `edk2-ovmf` package. On other distros, find a similar package and modify the path in the command accordingly.
2. Run the command above.
