[PATCH][5.10, 5.15, 6.1][0/1] hrtimer: Ignore slack time for RT tasks

This suggests a fix from 6.3 for stable that fixes a nasty bug in the
timing behavior of periodic RT tasks w.r.t timerslack_ns. While the
documentation clearly states that the slack time is ignored for RT tasks,
this is not the case for the hrtimer code. This patch fixes the issue and
applies to all stable kernels.
