[CI][14/N] Remove unnecessary "if" condition
It was left from
```
if: |
github.event.pull_request.head.repo.full_name == 'intel/llvm' ||
!contains(needs.detect_changes.outputs.filters, 'ci')
```
in the current pre-commit which wasn't needed with the pull_request
trigger. Also, keeping only one of two conditions was plain wrong.
