drm/i915: fix pm refcounting on fence error in execbuf

Browse source

Fences are creted/checked before the pm ref is taken, so if we jump to
pre_mutex_err we will uncorrectly call intel_runtime_pm_put.

v2: Massage unwind error paths

Fixes: fec0445caa (drm/i915: Support explicit fencing for execbuf)
