sandbox: terminate os_dirent_ls() result list
Each node in the linked-list that os_dirent_ls() returns has its next pointer set only when the next node is created. For the last node in the list, there is no next node, so this never happens, and the next pointer is never initialized. Explicitly initialize the next pointer so that it isn't dangling. Without this, "sb ls" might crash. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>
