drm/xe/pxp: Clean up termination status on failure

If the PXP HW termination fails during PXP start, the normal completion
code won't be called, so the termination will remain uncomplete. To avoid
unnecessary waits, mark the termination as completed from the error path.
Note that we already do this if the termination fails when handling a
termination irq from the HW.
