[PATCH v6 4/4] drm/xe/gt: Report GT reset failure using SIGID

[Arvind Yadav <arvind.yadav@intel.com>]

Route the GT reset failure log through the structured SIGID logging helper.

Failure to complete the full graphics reset means GT reset did not finish
as expected. Use the GT component, which maps to XE_SIGID_GT_TDR, and pass
the reset errno value to the helper.

Also update the message to describe the actual failure. The driver does not
clear GRDOM_FULL directly. the reset should complete and clear it within
the timeout.
