Subject: [PATCH] media: qcom: iris: fix runtime PM reference leaks

Use pm_runtime_resume_and_get() in iris_enable_power_domains()
to avoid leaking a runtime PM usage count on failure.

Also ensure pm_runtime_put_sync() is always called in
iris_disable_power_domains(), even when iris_opp_set_rate()
fails, so runtime PM references remain balanced.
