revert ucx upgrade (#12105)

<!--

Thank you for contributing to RAPIDS Accelerator for Apache Spark!

Here are some guidelines to help the review process go smoothly.

1. Please write a description in this text box of the changes that are
being
   made.

2. Please ensure that you have written units tests for the changes
made/features
   added.

3. If you are closing an issue please use one of the automatic closing
words as
noted here:
https://help.github.com/articles/closing-issues-using-keywords/

4. If your pull request is not ready for review but you want to make use
of the
continuous integration testing facilities please label it with `[WIP]`.

5. If your pull request is ready to be reviewed without requiring
additional
   work on top of it, then remove the `[WIP]` label (if present).

6. Once all work has been done and review has taken place please do not
add
features or make changes out of the scope of those requested by the
reviewer
(doing this just add delays as already reviewed code ends up having to
be
re-reviewed/it is hard to tell what is new etc!). Further, please avoid
rebasing your branch during the review process, as this causes the
context
of any comments made by reviewers to be lost. If conflicts occur during
review then they should be resolved by merging into the branch used for
   making the pull request.

Many thanks in advance for your cooperation!

Reverts #12058

The above PR was found to break `ucx_perftest` with `-m cuda` in the
ubuntu rdma container in a CI test. This is caused specifically by the
CUDA version upgrade in the PR.
