wifi: mac80211_hwsim: fully initialise PMSR capabilities
Since the recent additions to PMSR capabilities, it's no longer
sufficient to call parse_pmsr_capa() here since the capabilities
that were added aren't represented/filled by it. Always init the
data to zero to avoid using uninitialized memory.
Fixes: 86c6b6e4d187 ("wifi: nl80211/cfg80211: add new FTM capabilities")
