make gate-tempest-dsvm-ironic-pxe_ssh non voting

Currently this is wedging all number of things because ironic is using
diskimage builder to pull things from ubuntu upstream and a name
change in their images meant things no longer SHA256 correctly.

We should make this non-voting to fix things, and ensure we're not
making it voting again until this is no longer pulling from the open
internet.
