    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
