RecoverPreparedTransactions calls ProcessRecords with
twophase_recover_callbacks right after releasing the TwoPhaseStateLock, so I
think lock_held should be false here (matching the similar call of
TwoPhaseGetDummyProc at lock_twophase_recover).
Since the patch touches TwoPhaseGetDummyBackendId, let’s fix the comment
header to mention it instead of TwoPhaseGetDummyProc
