Fix description of WAL record XLOG_BTREE_META_CLEANUP
This record uses one metadata buffer and registers some data associated
to the buffer, but when parsing the record for its description a direct
access to the record data was done, but there is none. This leads
usually to an incorrect description, but can also cause crashes like in
pg_waldump. Instead, fix things so as the parsing uses the data
associated to the metadata block.
This is an oversight from 3d92796, so backpatch down to 11.
