[PATCH] drm: qxl: Fix NULL pointer dereference at qxl_alloc_client_monitors_config

The OOM notifier is getting deprecated to use for the reasons mentioned here by Michal Hocko: https://lkml.org/lkml/2018/7/12/314 This patch replaces the virtio-balloon oom notifier with a shrinker to release balloon pages on memory pressure. In addition, the bug in the replaced virtballoon_oom_n
