nl80211: Fix sizeof check in vendor command/event handling

Browse Source 
Fix sizeof in a validity comparison of nl80211_vendor_cmd_info size. The
incorrect version happened to work on 64-bit builds due the structure
being eight octets, but this was incorrect and would not used with
32-bit builds.
