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.
