[PATCH] aio: remove ki_retried debugging member
Remove the ki_retried member from struct kiocb. I think the idea was
bounced around a while back, but Arnaldo pointed out another reason that we
should dig it up when he pointed out that the last cacheline of struct
kiocb only contains 4 bytes. By removing the debugging member, we save
more than the 8 byte on 64 bit machines.
