LU-16096 target: use lsd_reply_data_v1 format by default

Since it does not actually need the lrd_batch_idx field in the
reply data for the read-only batched RPC such as statahead, this
means that lsd_reply_data_v2 format can be only enabled after the
update batched RPC such as MetaWBC is introduced.

In this patch, we use lsd_reply_data_v1 format and read/write
"REPLY_DATA" in old format by default.
