Indeed. Maybe the cap_list copy should be within the function, and
then define the function as:
static bool migrate_caps_check(MigrationCapabilityStatusList *params,
Error **errp);
Then it at least looks more like the param_check one.
Let me know if you think it's good; I can post another one after
