tests: Check more details in pmksa_cache_ap_expiration

Browse source 
It looks like this test case can fail if the STA goes to power save mode
and the Deauthentication frame from the AP after session timeout is not
actually sent at all. Check more details to make it clear that this is
indeed the reason behind the failure.
