renames is_last_in_fec_set back to is_last_data (#15848) (#16075)

https://github.com/solana-labs/solana/pull/10095
renamed is_last_data to is_last_in_fec_set. However, the code shows that
this is actually meant to indicate where the serialized data is
complete:
https://github.com/solana-labs/solana/blob/420174d3d/ledger/src/shred.rs#L599-L600
https://github.com/solana-labs/solana/blob/420174d3d/ledger/src/shred.rs#L229-L231

There are multiple FEC sets for each `&[Entry]` serialized and this flag
does not represent shreds last in FEC sets (only the very last one by
overlap). So the name is wrong and confusing

(cherry picked from commit 3b85cbc504)
