Added all ti vga queue. thanks, Gerd
These security issue is low severity and is similar with the virtio-vga/virtio-gpu device. All of them can be triggered by the guest user. Change since v1: Add the CVE information: Several memory leak issues is combined assigned CVE-2021-3544. Information disclosure is assigned CVE-2021-3545. OOB memory write access is assigned CVE-2021-3545. Abstract 'vg_cleanup_mapping_iov' to make code more clearly.
