btrfs: remove unused parameter from readahead_tree_block
The parent_transid parameter has been unused since its introduction in
ca7a79ad8dbe2466 ("Pass down the expected generation number when reading
tree blocks"). In reada_tree_block, it was even wrongly set to leafsize.
Transid check is done in the proper read and readahead ignores errors.
