Andrew Bartlett f4ff9a0794 lib/fuzzing: Also confirm we can make a string filter from the parsed tree in fuzz_ldb_parse_tree
This also avoids tree being an unused variable.

This is similar to doing an ndr_push() in ndr_fuzz_X, it
catches some of the cases where the parse is successful but
the application code could misinterpret the structure.
