Subject: [RESEND PATCH v2 17/19] io_uring: Switch to use hrtimer_setup_on_stack()
hrtimer_setup_on_stack() takes the callback function pointer as argument
and initializes the timer completely.
Replace hrtimer_init_on_stack() and the open coded initialization of
hrtimer::function with the new setup mechanism.
