Summary: A race condition will happen when: * a user thread writes a value, but it hits the write stop condition because there are too many un-flushed memtables, while holding blob_db_impl.write_mutex_. * Flush is triggered and call flush begin listener and try to acquire blob_db_impl.write_mutex_. Fixing it. Closes #3149 Differential Revision: D6279805 Pulled By: yiwu-arbug fbshipit-source-id: 0e3c58afb78795ebe3360a2c69e05651e3908c40
