[Crash-utility] A possible "dev -d" fix for newer kernels

I noticed that on newer kernels, the "dev -d" command is failing. Seems like the 'rq' field in the request_queue structure is now called 'root_rl'. The little change in the patch below seems to fix this problem, at least for me on i686 & x86_64.
