aio-dio-extend-stat test in aio_dio_bugs failed on s390x

[Po-Hsu Lin]

It can be reproduced on zVM, zKVM and Ubuntu on LPAR

This should not be considered as a regression, the test suite stopped on the first test in this test suite before.

Steps:
1. git clone --depth=1 https://github.com/autotest/autotest-client-tests.git
2. make -C autotest-client-tests/aio_dio_bugs/src
3. sudo ./autotest-client-tests/aio_dio_bugs/src/aio-dio-extend-stat file
