[PATCH v2 17/31] fork: Switch to use hrtimer_setup()

[Nam Cao]

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.
