Avoid adding duplicated BrokerEntryMetadata (apache#12018)

### Motivation

When the Pulsar cluster enables broker entry metadata, sometimes there're some corrupted entries. See streamnative/kop#442 for example. It's because the broker entry metadata has been added twice.

This bug might be introduced from apache#9039 https://github.com/apache/pulsar/blob/9b7c3275c904ac1e6a8ef67487a10a0506bb2c58/managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/ManagedLedgerImpl.java#L1516-L1518

It happened during a managed ledger's rollover while there're some pending `OpAddEntry`s in `updateLedgersIdsComplete`, only the ledger id should be updated and the data of `OpAddEntry` should not be modified.

### Modifications

Only call `beforeAddEntry` for once at the beginning of `internalAsyncAddEntry`.
