xen/gntdev: do not set VM_PFNMAP Since we are using the m2p_override we do have struct pages corresponding to the user vma mmap'ed by gntdev. Removing the VM_PFNMAP flag makes get_user_pages work on that vma. An example test case would be using a Xen userspace block backend (QDISK) on a file on NFS using O_DIRECT.
