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.
