    tracing/osnoise: Switch to use hrtimer_setup()

    hrtimer_setup() takes the callback function pointer as argument and
    initializes the timer completely.

    Replace hrtimer_init() and the open coded initialization of
    hrtimer::function with the new setup mechanism.

    Patch was created by using Coccinelle.
