kernel: drm/virtio: use uninterruptible resv lock for plane updates

A flaw was found in the Linux kernel's VirtIO GPU Graphics Processing Unit driver. The virtiogpucursorplaneupdate and virtiogpuresourceflush functions fail to properly acquire a required lock, which can lead to a race condition. A local user could exploit this vulnerability by triggering a memory...
