Revert "[QNN EP] Clean up correctly from a partial setup (#23320)" (#23420)

### Description
<!-- Describe your changes. -->

This reverts commit 5d215ff.

### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->

The reverted change causes a packaging pipeline to fail due to a crash
in one of the E2E Android tests.

Reverting this first to fix the pipeline. We should come up with an
alternative way to properly do the necessary clean up.
