* @brief Search for a mount point associated with a specific device ID in the mount tree. * * This function initiates a search for a mount point that is associated with the specified * device ID `dev_id` starting from the root mount point. It first checks the root mount point * directly, and if not found, it recursively searches the entire mount tree using the * internal helper function `_dfs

 *         Otherwise, returns RT_NULL.
