This patchset tries to add new IO_URING test into fsstress [1/4] and fsx [4/4].
And then do some changes and bug fix by the way [2/4 and 3/4].

fsstress and fsx are important tools in xfstests to do filesystem I/Os test,
lots of test cases use it. So add IO_URING operation into fsstress and fsx
will help to cover IO_URING test from fs side.

I'm not an IO_URING expert, so cc io-uring@ list, please feel free to
tell me if you find something wrong or have any suggestions to improve
the test.

Thanks,
Zorro
