hrtimers: Make hrtimer_update_function() less expensive
commit 2ea97b76d6712bfb0408e5b81ffd7bc4551d3153 upstream.
The sanity checks in hrtimer_update_function() are expensive for high
frequency usage like in the io/uring code due to locking.
Hide the sanity checks behind CONFIG_PROVE_LOCKING, which has a decent
chance to be enabled on a regular basis for testing.
