ci: cram: pwhm-usp.t test script is executed twice

Problem:

The revert of MR !2395 is incomplete. It added the new
103-pwhm-usp.t symlink but kept the previous 102-pwhm-usp.t symlink.

As a result, both symlinks point to the same script, causing the
pwhm-usp test to be executed twice in the same test run. Running the
script twice in a row without delay is unreliable and may lead to some
failures.

Solution:

- Remove the obsolete 102-pwhm-usp.t symlink so only 103-pwhm-usp.t
remains.
- Ensure the AccessPoint is disabled before starting the test.
