Bug description:
[Impact]
The updated LTP has added proc_sched_rt01 testcase which can't pass
since several commits are missed from kernel side.

[Fix]
There are 3 relevant commits from upstream.
1. 079be8fc6309 sched/rt: Disallow writing invalid values to sched_rt_period_us
2. c1fc6484e1fb sched/rt: sysctl_sched_rr_timeslice show default timeslice after reset
3. c7fcb99877f9 sched/rt: Fix sysctl_sched_rr_timeslice intial value
Mantic: the 3rd is already in master-next.
Jammy: stable v5.15.150 includes the three commits.
Focal: master-next has include them after update to v5.4.270
Bionic: all the three commits are needed.
[Test case]
Run LTP update 20240312 to check the log of proc_sched_rt01.
[Regression potential]
Low risk since these content are existed in upstream for a while.

sched/rt: sysctl_sched_rr_timeslice show default timeslice after reset
