I wonder if we really need this.  My idea would have been to just
branch out to the fabrics command parser from parse_nvme_cmd().  Or did
I miss something why that might not work?

The benefit is that we don't have an additional branch in the
non-tracing fast path (and also make it look a little nicer).

Why do we need this #define to the same name/signature?
