Bob Copeland f068272cb2 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.
