CVE-2021-46967 vhost-vdpa: fix vm_flags for virtqueue doorbell mapping

In the Linux kernel, the following vulnerability has been resolved: vhost-vdpa: fix vmflags for virtqueue doorbell mapping The virtqueue doorbell is usually implemented via registeres but we don't provide the necessary vma-flags like VMPFNMAP. This may cause several issues e.g when userspace trie...
