Use goto to cleanup error handling in readSyncBulkPayload

[enjoy-binbin]

The goto error label is the same as the error return, use goto to reduce the references.

error:
    cancelReplicationHandshake(1);
    return;

Also this can make the log printing more continuous under the error, that is, we print the error log first, and then print the reconnecting log at the last (in cancelReplicationHandshake).

67697:S 21 Nov 2024 16:01:03.310 * Reconnecting to PRIMARY 127.0.0.1:6379 after failure
67697:S 21 Nov 2024 16:01:03.310 * PRIMARY <-> REPLICA sync started
67697:S 21 Nov 2024 16:01:03.310 * PRIMARY <-> REPLICA sync: Discarding the half-loaded data

the reconnecting and sync started should be after discarding one.

cancelReplicationHandshake is a no-op in some cases where we just did return before, right?

no, cancelReplicationHandshake is not a no-op, and we are not just did return before, we did cancelReplicationHandshake and return together before, this commit just like, adjust the code location (or order).

Ah, I see now. Every goto error replaces cancelReplicationHandshake + return.
