Yanqin Jin 1e87f2b68b Ref and unref cfd before and after calling WaitForFlushMemTables (#5513) 
Summary:
This is to prevent bg flush thread from unrefing and deleting the cfd that has been dropped by a concurrent thread.
Before RocksDB calls `DBImpl::WaitForFlushMemTables`, we should increase the refcount of each `ColumnFamilyData` so that its ref count will not drop to 0 even if the column family is dropped by another thread. Otherwise the bg flush thread can deref the cfd and deletes it, causing a segfault in `WaitForFlushMemtables` upon accessing `cfd`.

Test plan (on devserver):
```
$make clean && COMPILE_WITH_ASAN=1 make -j32
$make check
```
All unit tests must pass.
