wlantest: Do not report PMF failure without BSS supporting PMF

Previously, missing CCMP protection on Robust Management frames was
reported based on the STA having indicated MFPC=1. That is not accurate
since the AP/BSS may have MFPC=0. Report this failure only if both the
AP and STA have indicated MFPC=1, i.e., when PMF has been negotiated for
the association.
