My (mild) preference for folding "update_domain_attr()" into
"update_domain_attr_tree()" was not to save runtime CPU cycles.
This is not a hot code path.  It was to improve code readability.

Do what you think is best here ... I'm easy.

Then perhaps one could include in the comment for
"update_domain_attr_tree()" that it is a helper function
for rebuild_sched_domains(), where its locking is described.
