w/o sugov tasks:
The issue seems to be that we call partition_sched_domains() for CPU4
during suspend. Which does not issue a:
build_sched_domains() -> cpu_attach_domain() -> rq_attach_root() ->
__dl_server_[de|at]tach_root()

[ 171.008069] Error taking CPU3 down: -16
You can see how 'dl_b->total_bw' stays 104856 (2 x util = 51) even
though CPU4 is off (*).
If total_bw would be 52428 for CPU3 going down we would still fail with
the current code (taking the else path):
3604 if (dl_bw_cpus(cpu) - 1)
3605 overflow = __dl_overflow(dl_b, cap, fair_server_bw, 0);
3606 else
3607 overflow = 1;
but if we would take the if path even when 'dl_bw_cpus(cpu) = 1'
_dl_overflow() would return false:
280 return dl_b->bw != -1 &&
281 cap_scale(dl_b->bw, cap) < dl_b->total_bw - old_bw + new_bw;
'0 < 52428 - 52428 + 0' is false
