drm/xe/guc: distinguish wedged from recoverable cancellation

Browse source

The CT layer returns -ECANCELED regardless of whether cancellation
is due to a GT reset or a wedged device. Return -ENOTRECOVERABLE
on wedge so callers don't need xe_device_wedged() checks
to suppress spurious error logs.
Also document the return codes of xe_guc_ct_send() in kernel-doc form.
