[PATCH v1] drm/xe/ras: Fix sysctrl and drm-ras discrepancy

[Raag Jadav <raag.jadav@intel.com>]

There are cases where a reported error is valid for sysctrl but it's not
exposed as a valid uapi through drm-ras. We allow such error to be logged
but it's redundant to try to send an error-event for it. Early return such
cases and prevent misleading drm-ras error-event failures.

Fixes: 6a9493e47075 ("drm/xe/xe_ras: Report correctable/uncorrectable error events to userspace")
