tests: Fix pasn_sae_driver to clear PTKSA cache after first PASN exchange

The test pasn_sae_driver triggers PASN for the same peers twice. In the
current implementation, when PASN succeeds, the keys generated are
stored in the PTKSA cache.

The function wpas_pasn_configure_next_peer() shows an issue where it
does not reuse keys from a previous PASN exchange, even when those keys
are available in the cache. Instead, it initiates a new PASN exchange
unnecessarily.

Fix the test case by deleting the keys from the cache after the first
PASN attempt. This ensures a full PASN exchange can occur again. A
subsequent commit will address the API behavior to reuse keys from the
cache when available.
