Lyude Paul 23b128bba7 rust: time: Pass correct timer mode ID to hrtimer_start_range_ns
While rebasing rvkms I noticed that timers I was setting seemed to have
pretty random timer values that amounted slightly over 2x the time value I
set each time. After a lot of debugging, I finally managed to figure out
why: it seems that since we moved to Instant and Delta, we mistakenly
began passing the clocksource ID to hrtimer_start_range_ns, when we should
be passing the timer mode instead. Presumably, this works fine for simple
relative timers - but immediately breaks on other types of timers.

So, fix this by passing the ID for the timer mode instead.
