commit 21f1435b1e6b012a07c42f36b206d2b66fc8f13b upstream. If the active performance monitor (`v3d->active_perfmon`) is being destroyed, stop it first. Currently, the active perfmon is not stopped during destruction, leaving the `v3d->active_perfmon` pointer stale. This can lead to undefined behavior and instability. This patch ensures that the active perfmon is stopped before being destroyed, aligning with the behavior introduced in commit 7d1fd363 ("drm/v3d: Stop the active perfmon before being destroyed").
