aio_cancel: wait for requests which are already in progress
If request is already in progress, wait for it to complete,
so it doesn't race with exit of testcase (aiocb is allocated
on main's stack), to avoid aio_cancel_1-1 and 2-1 sporadically
crashing.
For example:
Core was generated by `./aio_cancel_2-1.run-test '.
Program terminated with signal 11, Segmentation fault.
