Remove unsafe timer_pending() check in taskq_cancel_id() that created a race where: - Timer expires and timer_pending() returns FALSE - task_done() frees task with tqent_func = NULL - Timer callback executes and queues freed task - Worker thread crashes executing NULL function Always call timer_delete_sync() unconditionally to ensure timer callback completes before task is freed. Reliably reproducible by injecting mdelay(10) after setting CANCEL flag to widen the race window, combined with frequent task cancellations (e.g., snapshot automount expiry).
