io_uring: Use helper function hrtimer_update_function()
The field 'function' of struct hrtimer should not be changed directly, as
the write is lockless and a concurrent timer expiry might end up using the
wrong function pointer.
Switch to use hrtimer_update_function() which also performs runtime checks
that it is safe to modify the callback.
