Yuri Benditovich 61193f9cab Fix for black screen on driver uninstall on ovmf platform
https://bugzilla.redhat.com/show_bug.cgi?id=1661147
If display miniport driver does not pass valid display info to
the basic display driver on disable/uninstall, the basic
display driver raises run-time error and stays with yellow
bang. This behavior is specific to UEFI machines.
