[PATCH v3 2/2] media: qcom: iris: rollback OPP vote on PM resume failure

[Hungyu Lin]

Rollback the maximum OPP vote when
pm_runtime_resume_and_get() fails in
iris_enable_power_domains().

This ensures the performance state vote is released when
power domain enablement does not complete successfully.

Fixes: bb8a95aa038e ("media: iris: implement power management")
