sched/fair: fix kabi broken due to adding fields in rq and sched_domain_shared 

hulk inclusion
category: bugfix
bugzilla: 38261, https://bugzilla.openeuler.org/show_bug.cgi?id=23


CVE: NA

---------------------------

Previous patches added fields in struct rq and sched_domain_shared,
which caused the KABI changed.

We can use some helper structures to fix this KABI change, but this is
not necessary, because these structures are only used internally, the
driver is not aware of them, so we simply avoid them.
