[issue1528] ktrace does not show proper return values for pipe(2)

[Stathis Kamperis (via DragonFly issue tracker)]

Stathis Kamperis <ekamperi at gmail.com> added the comment:

I've added a kprintf in ktrsysret() and here is what printed:

1126 a.out   CALL pipe
1126 a.out   RET  ret=3 error=0 code=42 pipe 3

Question is why `ret' contains the first file descriptor of the pair at all.
(and not zero as ought to)
