hrtimers: Introduce hrtimer_update_function()
Some users of hrtimer need to change the callback function after the
initial setup. They write to hrtimer::function directly.
That's not safe under all circumstances as the write is lockless and a
concurrent timer expiry might end up using the wrong function pointer.
Introduce hrtimer_update_function(), which also performs runtime checks
whether it is safe to modify the callback.
This allows to make hrtimer::function private once all users are converted.
