Modified Files:
        src/sys/ufs/ext2fs: ext2fs_vfsops.c

Log Message:
Several fixes:
 - rename ext2fs_checksb() -> ext2fs_sbcheck(): more consistent
 - in ext2fs_sbcheck(), add a check to ensure e2fs_inode_size!=0,
   otherwise division by zero
 - add ext2fs_sbcompute(), to compute dynamic values of the superblock.
   It is done twice in _reload() and _mountfs(), so put it in a function.
 - reorder the code in charge of loading the superblock: now, read the
   superblock, swap it directly, and *then* pass it to ext2fs_sbcheck().
   It is similar to what ffs now does. It is better since the fields don't
   need to be swapped on the fly in ext2fs_sbcheck().
Tested on amd64.
