sqfs_dir_tree_destroy/sqfs_destroy: allow NULL input
Many library destructor functions (like free()) allow a NULL pointer as input, and do nothing in that case. This allows easier cleanup patterns: initialize pointers to NULL and then always pass them to the destroyer functions, no need for verbose goto/if-else patterns.
