User Pierre Guinoiseau reported on the mailing lists  that after the last update to the collectd5 port the disk module stopped reporting statistics it used to report.
I think the attached patch fixes the issue. Last update to the port removed a patch which is actually needed.
I'm adding Pierre and the port maintainer as CCs to this bug for testing and approval.
