            Log:
            improve the incorrectly written io_uring checks

I wrote certain io_uring checks incorrectly, because I misunderstood
the comments in the RHEL-11792 ticket. They should be correct now.

In order to properly test the io_uring feature, the feature needs to
be enabled (it is by default on Fedora). If the kernel command line
does not contain the "io_uring" string, the automated test adds the
necessary options and reboots the machine.
