* @brief Destroy a dfs_mnt structure instance and unmount it if necessary. * * This function attempts to destroy the specified dfs_mnt structure instance. * If the mount point is currently mounted, it marks the mount point as unmounted, * sets the unmount flag, and removes it from the mount list if it was added. * Finally, it decreases the reference count of the mount point and frees the * s

 * @return Returns RT_EOK to indicate success.
