That way the test will leave enabled io_uring after the test run.
Need to restore the value which was prior the test running - in case the test
does not fail at least.
not tested!

selftests: net: io_uring_zerocopy.sh: restore io_uring sysctl on exit
Save the original value of kernel.io_uring_disabled before changing
it and restore it in cleanup handler to ensure the system state is
restored regardless of test outcome.

The io_uring_zerocopy.sh kselftest assumes that io_uring support is
enabled on the host system. When io_uring is disabled via the
kernel.io_uring_disabled sysctl, the test fails.
Explicitly enable io_uring for the test by setting
kernel.io_uring_disabled=0
