Merged into next. Thanks!

The kernel might check for a valid context before checking the access of the pointers. In such a case, it will return EINVAL instead of EFAULT. Add an io_setup step to the test to ensure the io_cancel syscall fails because of the intended cause.

This patch doesn't have any dependency, but it's a dependency to the following Morello Linux series: "Support aio shared memory usage in the Purecap apps"
v3..v4:
- Remove memset from io_cancel02
v2..v3:
- Apply a similar change to io_cancel02.c as well
