sched/deadline: Reset extra_bw to max_bw when clearing root domains
dl_clear_root_domain() doesn't take into account the fact that per-rq
extra_bw variables retain values computed before root domain changes,
resulting in broken accounting.
Fix it by resetting extra_bw to max_bw before restoring back dl-servers
contributions.
Fixes: 2ff899e351643 ("sched/deadline: Rebuild root domain accounting after every update")
