cfg80211/mac80211: clean up cfg80211 SME APIs
Do some cleanups in the cfg80211 SME APIs, which are only used by mac80211. Most of these functions get a frame passed, and there isn't really any reason to export multiple functions as cfg80211 can check the frame type instead, do that. Additionally, the API functions have confusing names like cfg80211_send_...() which was meant to indicate that it sends an event to userspace, but gets a bit confusing when there's both TX and RX and they're not all clearly labeled.
