[PATCH 05/12] io_uring: Use helper function hrtimer_update_function()

[Nam Cao]

There is a new helper function hrtimer_update_function() to change the
hrtimer's callback function, which also performs additional runtime check
that it is safe to change the callback.

Use the helper function instead of accessing 'function' directly.
