LU-16096 recovery: upgrade reply data after recovery finish

As the batched RPC protocol will change the disk format of the
client reply data "REPLY_DATA" for recovery, thus we need to
handle the compatibility during upgrade carefully for this new
format change of the reply data.

The solution is as follows:
When the client recovery has finished, the target truncates the
reply data file with zero size and rewrite the header to use the
new magic and reply data record size.
And then new reply data records will be written in the new format.

Enable the test case conf-sanity/32, 108 as the compatibility issue
is fixed.

This patch also fixes the usage of struct lsd_reply_data in
lustre/utils/lr_reader.c to support both struct versions.
