perf: Identify the 0->1 transition for event::mmap_count
Needed because refcount_inc() doesn't allow the 0->1 transition.
Specifically, this is the case where we've created the RB, this means
there was no RB, and as such there could not have been an mmap.
Additionally we hold mmap_mutex to serialize everything.
This must be the first.
