[PATCH 1/3] media: iris: Fix runtime PM reference imbalance on failed resume

[Vishnu Reddy]

pm_runtime_resume_and_get() drops its usage count when the resume
fails. iris_hfi_queue_cmd_write() dropped it a second time on that
path, resulting in a runtime PM usage count underflow warning:

  qcom-iris aa00000.video-codec: Runtime PM usage count underflow!
