Christian GmeinerandGreg Kroah-Hartman eb0e0eca0e drm/v3d: Stop active perfmon if it is being destroyed ...

commit 21f1435b1e 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
7d1fd3638e ("drm/v3d: Stop the active perfmon before being destroyed").
