selftests: net: io_uring_zerocopy: enable io_uring for the test
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.
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.
