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.
