x86/uaccess: fix sparse errors
virtio wants to read bitwise types from userspace using get_user. At the moment this triggers sparse errors, since the value is passed through an integer. Fix that up using __force. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Thomas Gleixner <tglx@linutronix.de>
