log spamming in db_impl_files.cc

### Expected behavior
No warnings.

### Actual behavior
Log spamming, with the following 2 messages repeated hundreds of times per day:

[/db_impl/db_impl_files.cc:94] File Deletions Enable, but not really enabled. Counter: 1
[/db_impl/db_impl_files.cc:54] File Deletions Disabled, but already disabled. Counter: 1

### Steps to reproduce the behavior
We are using Rocksdb in Java (6.2xx): these logs are happening even with a simple unit test with open a database, write some keys, then close it.
