Revert usage of Defer. (#6410)

Summary:
Seems like this caused the following test failure on AppVeyor:
DBTest2.CrashInRecoveryMultipleCF
c:\projects\rocksdb\db\db_test_util.cc(107): error: DestroyDB(dbname_, options)
IO error: Failed to delete: C:\projects\rocksdb\db_tests\\testrocksdb-3112//db_test2_10791409581227174103/000013.sst: Access is denied.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6410

Test Plan: Wait to see whether the AppVeyor test passes.
