In order to support multiple nla_parse function signatures across different kernel versions, a new wlan_cfg80211_nla_parse wrapper was introduced. However, it is easy for propagations or new code to reintroduce nla_parse. Redefine nla_parse to throw an error, to prevent the function from being reintroduced into the code base.
