Every tracing file must have its own TRACE_SYSTEM defined.
The mac80211 tracepoint header broke this and add in the middle
of the file had:

 #undef TRACE_SYSTEM
 #define TRACE_SYSTEM mac80211_msg

Unfortunately, this broke new code in the ftrace infrastructure.
Moving the mac80211_msg into its own trace file with its own
TRACE_SYSTEM defined fixes the issue.
