[Qemu-devel] [PATCH] linux-user: Fix type for SIOCATMARK ioctl |

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.

This fixes a failure in the LTP sockioctl01 test.
