[PATCH] ext2 endianness fixes

Several places printk a little-endian number without any conversions.
Ones in super.c are particulary unpleasant - there we are getting told that
fs couldn't be mounted because of the following set of incompat features
and it would be nice to have the printed number matching what one could
find in headers...
