fix deserializeBrokerEntryMetaDataFirst not found (apache#11220)

### Motivation

apache#11014 introduced `getEntryTimestamp` and removed `deserializeBrokerEntryMetaDataFirst`, but apache#11139 is still using `deserializeBrokerEntryMetaDataFirst`, and it breaks master branch.

### Modifications

use `entryTimestamp` for expiry checking in `internalGetMessageIdByTimestamp`
