linux-user: Fix type for SIOCATMARK ioctl

qemu with hax to log dma reads & writes jcs.org/2018/11/12/vfio

The SIOCATMARK ioctl takes an argument which should be a
pointer to an integer where the kernel will write the result.
We were incorrectly declaring it as TYPE_NULL which would mean
it would always fail (with EFAULT) when it should succeed.
Correct the type.
