MSIR.0826 NONPRE doesn't make sense for DISALLOW

A SIRMETH DISALLOW command was issued with a NONPRE qualifier on a subsystem name. Since non-pre-compiled requests in a subsystem have no privileges to set globals, it doesn't make sense to disallow it.

If the intent was to remove privileges granted to non-pre-compiled requests via a previous SIRMETH ALLOW command, the SIRMETH ALLOW command should be re-issued without the NONPRE keyword, or a SIRMETH ALLOW command should be issued without the NONPRE keyword for the subset of the subsystems for which privileges are to be removed from non-pre-compiled requests.
