Don't crash if s_inode_size is zero

Any attempt to open a filesystem with s_inode_size set to zero causes
a floating point exception.  This is true for e2fsck, dumpe2fs,
e2image, etc.  Fix ext2fs_open2() so that it returns the error code
EXT2_ET_CORRUPT_SUPERBLOCK instead of crashing.

Thanks to Dean Bender for reporting this bug.
