[PATCH] ext3: multile block allocate little endian fixes

Some places in ext3 multiple block allocation code (in 2.6.17-rc3) don't
handle the little endian well.  This was resulting in *wrong* block numbers
being assigned to in-memory block variables and then stored on disk
eventually.  The following patch has been verified to fix an ext3
filesystem failure when run ltp test on a 64 bit machine.
