To remove the file_priv NULL-ing dance needed to check if the file descriptor is open, move the per-fd reset counter into v3d_stats, which is heap-allocated and refcounted, outliving the fd as long as jobs reference it. This change allows the removal of the last `queue_lock` usage to protect `job->file_priv` and avoids possible NULL ptr dereference issues due to lifetime mismatches. Also, to simplify locking, replace both the global and per-fd locked reset counters with atomics.
