tracepoints: Code clean up

Restructure the code a bit to make it simpler, fix some formatting problems
and add READ_ONCE/WRITE_ONCE to make sure there's no compiler load/store
tearing to the variables that can be accessed across CPUs.

Started with Mathieu Desnoyers's patch:

And will keep his signature, but I will take the responsibility of this
being correct, and keep the authorship.
