[PATCH v2 12/16] tracing: Mark the tracing_gen_ctx helpers notrace

[Song Liu]

tracing_gen_ctx(), tracing_gen_ctx_flags() and tracing_gen_ctx_dec()
are called by ftrace callbacks before they take any recursion
protection, for example function_test_events_call() in
kernel/trace/trace_events.c, which is built with -pg when
CONFIG_FUNCTION_SELF_TRACING=y. They are plain inline functions, so an
out-of-line copy is untraced only because inline implies notrace.

Mark them notrace explicitly. No functional change.
