struct trace_array is declared twice. One has been declared
at forward struct declaration. Remove the duplicate.
And sort these forward declarations alphabetically.

Um, no that's not how we sort things.

NAK to the above. If anything, we sort it by length. But the above doesn't
need to be touched.
