Subject: IGET: Fix isofs_get_block() to only return 0 on success.
From: David Howells <dhowells@xxxxxxxxxx>
Fix isofs_get_block() to return only 0 on success. It shouldn't return a
+ve block count for example.
Also make sure that isofs_get_blocks() doesn't accidentally return an error
if rv is 0 come the return statement.
