[PATCH] drm/xe/gt_pagefault: Print engine class string

[Francois Dugast]

The engine class index which is printed here is an internal representation
for debugging. It is _not_ an index based on DRM_XE_ENGINE_CLASS_* values
provided in the uAPI. Add the string representation of the engine class to
the output in order to limit possible confusion by users when analyzing the
logs.
