workqueue: Fix type of cpu in trace event
The trace event "workqueue_queue_work" use unsigned int type for
req_cpu, cpu. This casue confusing cpu number like below log.
$ cat /sys/kernel/debug/tracing/trace
cat-317 [001] ...: workqueue_queue_work: ... req_cpu=8192 cpu=
4294967295
So, change unsigned type to signed type in the trace event. After
applying this patch, cpu number will be printed as -1 instead of
4294967295 as folllows.
$ cat /sys/kernel/debug/tracing/trace
cat-1338 [002] ...: workqueue_queue_work: ... req_cpu=8192 cpu=-1
