drm/vmwgfx: Fix unlocked ioctl and add proper access control
This fixes up vmwgfx for the unlocked ioctl code to avoid doing it in the driver. Also adds ioctl flags. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Jakob Bornecrantz <jakob@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
