With host_mlme support being added mwifiex_cfg80211_ops is no longer constant, but supplemented with the host_mlme related ops when host_mlme support is enabled. This doesn't work with multiple adapters when only few of then have host_mlme support. Duplicate mwifiex_cfg80211_ops before using it and keep the original constant. While at it mark mwifiex_cfg80211_ops const to prevent people from changing it again during runtime.
