xen/gntdev: do not set VM_PFNMAP
commit e8e937be971d706061dc56220ff3605ab77622a7 upstream.
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.
