[PATCH] Fix IA64 success/failure indication in syscall auditing. 

Original 2.6.9 patch and explanation from somewhere within HP via
bugzilla...

ia64 stores a success/failure code in r10, and the return value (normal
return, or *positive* errno) in r8. The patch also sets the exit code to
negative errno if it's a failure result for consistency with other
architectures.
