drm/i915/guc: Unwind GuC workqueue reservation if request construction
fails
We reserve space in the GuC workqueue for submitting the request in the
future. However, if we fail to construct the request, we need to give
that reserved space back to the system.
Fixes: dadd481bfe55 ("drm/i915/guc: Prepare for nonblocking execbuf
submission")</pre>
