When rocksdb_create_column_family returns an error, it also returns a non-NULL pointer that needs to be freed. I have attempted to submit a fix for this upstream to RocksDB [1]. Add a check to free it if it returns a non-NULL pointer, which will work with older versions of RocksDB.
I believe this is the last of my set of fixes for valgrind reported memory leaks in the rust-rocksdb tests.
