drm/i915: don't enable PM_VEBOX_CS_ERROR_INTERRUPT
The code to handle it is broken - there's simply no code to clear CS
parser errors on gen5+. And behold, for all the other rings we also
don't enable it!
Leave the handling code itself in place just to be consistent with the
existing mess though. And in case someone feels like fixing it all up.
This has been errornously enabled in
