Remove unnecessary break in pg_logical_replication_slot_advance()
pg_logical_replication_slot_advance() included a break condition to stop
when a targeted LSN is reached, when processing a series of WAL records
with XLogReadRecord(). Since 38a957316d7e, it matched with the check of
its main while loop. This condition saved from an extra CFI check,
actually pointless, so let's remove this condition and simplify the
code.
In passing, fix an incorrect comment.
