[PATCH v2] sched/rt: remove empty sched_rt_do_global() helper

[Zhan Xusheng <zhanxusheng1024@gmail.com>]

sched_rt_do_global() is an empty helper that has no effect on
RT bandwidth sysctl handling.

Historically, sched_rt_do_global() was responsible for managing
RT throttling parameters before the introduction of the fair
server. Since commit 5f6bd380c7bd ("sched/rt: Remove default
bandwidth control"), the function became obsolete, but the empty
helper and its call site were retained.

Remove the unused function and its call site to simplify the
sysctl update path.

No functional change intended.
