Removing io_uring test from direct test case

Commit 8ad73bf was recently merged into master. There is an issue on
CentOS 9 that is causing failures with in CI build when using
--ioengine=io_uring. I have temporarily updated that direct test for FIO
asynchronous IO engines to use this same check to avoid CI failures till
this issue is resolved  and merged into master.
