[PATCHv4 07/12] sched: Change root_domain->overload type to int

[Morten Rasmussen <morten.rasmussen@arm.com>]

From: Valentin Schneider <valentin.schneider@arm.com>

sizeof(_Bool) is implementation defined, so let's just go with 'int' as
is done for other structures e.g. sched_domain_shared->has_idle_cores.

The local 'overload' variable used in update_sd_lb_stats can remain
bool, as it won't impact any struct layout and can be assigned to the
root_domain field.
