omfs: check bounds on block numbers before passing to sb_bread In case of filesystem corruption, passing unchecked block numbers into sb_bread can result in an infinite loop in __getblk(). Introduce a wrapper function omfs_sbread() to check the block numbers and to also perform the clus_to_blk() scaling. Signed-off-by: Bob Copeland <me@bobcopeland.com>
