    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")
