Fix the MultiGet testing failure in Circleci (#6578)

Browse Source 
Summary:
The MultiGet test in db_basic_test fails in CircleCI vs2019. The reason is that even Snappy compression is enabled, the first compression type is still kNoCompression. This PR checks the list and ensure that only when compression is enable and the compression type is valid, compression will be enabled. Such that, it will not fail the combined read test in MultiGet.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6578

Test Plan: make check, db_basic_test.
