Juri Lelli ac31ba7430 sched/deadline: Fix accounting after global limits change ...

[ Upstream commit 440989c10f ]

A global limits change (sched_rt_handler() logic) currently leaves stale
and/or incorrect values in variables related to accounting (e.g.
extra_bw).

Properly clean up per runqueue variables before implementing the change
and rebuild scheduling domains (so that accounting is also properly
restored) after such a change is complete.
