When an interrupt is received for correctable errors indicating that error

Also send drm-ras error-event to userspace for uncorrectable errors on
receiving an AER.
To avoid sending duplicate events when the same component appears multiple
times in the response, Send the error-event once per component.

Similar to threshold crossed case, we should probably have a BUILD_BUG_ON()
against XE_RAS_NUM_ERROR_ARR.
This is already added part of correctable. Seems unnecessary to add it twice
