[PATCH 4/7] drm/xe: Add XE_ENGINE_CLASS_OTHER to str conversion

[Lucas De Marchi <lucas.demarchi@intel.com>]

XE_ENGINE_CLASS_OTHER was missing from the str conversion. Add it and
remove the default handling so it's protected by -Wswitch-enum.
Currently the only user is xe_hw_engine_class_sysfs_init(), which
already skips XE_ENGINE_CLASS_OTHER, so there's no change in behavior.
