In the ranging use case, PASN is performed solely to derive and
install the encryption keys (TK) into the driver. Once set_keys()
has been called, the PMK and any cached PMKSA entry serve no further
purpose. Flush the PMKSA cache after get_ranging_params() is invoked
on both the initiator and responder to ensure the PMKID is not
included in M1 on any subsequent PASN attempt.
