Disable the GL scanout when the actively-displayed dmabuf is released,
so the console does not retain a stale reference.
Fixes: 239b7c5705a4 ("vfio/pci: close display console during unrealize,
not finalize")
Because the VFIO commit changes to call qemu_console_gl_release_dmabuf()
before qemu_graphic_console_close(), which dereferences the active scanout.
