I actually removed them because in order to satisfy them we have to
initialise rings we never use (and have another patch so that we only
intialise rings once inside intel_ringbuffer.c). We were causing extra
work for ourselves for no good reason.

And we need to cull the BUG_ONs for which a WARN and recovery would
serve better.
