[PATCH] media: qcom: iris: handle runtime PM resume failure in core deinit

[Hungyu Lin]

Check the return value of pm_runtime_resume_and_get() in
iris_core_deinit().

If runtime PM resume fails, avoid accessing hardware resources
and skip the corresponding pm_runtime_put_sync() call, preventing
unbalanced runtime PM references.
