Subject: [PATCH] Remove an assert that causes TSAN failure.

Summary:
ColumnFamilyData::ConstructNewMemtable is called out of DB mutex, and it asserts current_ is not empty, but current_ should only be accessed inside DB mutex. Remove this assert to make TSAN happy.
Closes https://github.com/facebook/rocksdb/pull/2235
