fs: reiserfs: remove unnecessary check of bh in remove_from_transaction()

On lines 3430-3434, bh has been assured to be non-null:
    cn = get_journal_hash_dev(sb, journal->j_hash_table, blocknr);
    if (!cn || !cn->bh) {
        return ret;
    bh = cn->bh;

Thus, the check of bh on line 3447 is unnecessary and can be removed.
Thank Andrew Morton for good advice.
