Fix multiple CF replay failure in db_bench replay (#6787)

Browse Source 
Summary:
The multiple CF hash map is not passed to the multi-thread worker. When using multi-thread replay for multiple CFs, it will cause segment fault. Pass the cf_map to the argument.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6787

Test Plan: pass trace replay test.
