Gyu-Ho Lee 26abd25cd3 mvcc/backend: hold 'readTx.Lock' until completing bolt.Tx reset

Fix https://github.com/coreos/etcd/issues/7526.

When resetting `bolt.Tx` in `defrag` and `batchTxBuffered.commit`
operation, we do not hold `readTx` lock, so the inflight range
requests can trigger panic in `mvcc.Range` paths. This fixes by
moving mutexes out and hold it while resetting the `readTx`.
