[PATCH v4 3/4] drm/xe/svm: Report terminal page-fault failures using SIGID

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

Route terminal SVM page-fault failures through the structured SIGID logging
helper.

These errors are reported only after the retry count is exceeded, so they
represent terminal page-fault handling failures rather than transient retry
conditions.

Use the PAGEFAULT component, which maps to XE_SIGID_MEM_FAULT, and pass the
real errno value to the helper. The helper renders the errno, so remove the
manual ERR_PTR() formatting from the message text.
